Joint Chiefs of Staff Chairman General Mark Milley confirmed on Wednesday he did speak to Chinese officials after a bombshell report claims he phoned his counterpart there over concerns then-President Trump would take rogue action to stay in office. Milley maintains in the statement that the calls were 'vital' to 'avoiding unintended consequences,' but seemed to dispute that they were done in secret. Multiple journalists posted the lengthy statement on Twitter, reportedly issued by Milley's spokesperson Colonel Dave Butler. 'The Chairman of the Joint Chiefs regularly communicates with Chiefs of Defense across the world, including with China and Russia ,' the statement began. 'These conversations remain vital to improving mutual understanding of U.S. national security interests, reducing tensions, providing clarity and avoiding unintended consequences or conflict. 'His calls with the Chinese and others in October and January were in keeping with these duties and responsibilities conveying reassurance in order to maintain strategic stability.' The first phone call reportedly took place days before the November election, and the second happened shortly after the Capitol riot. In his statement Milley claimed that the phone calls were done in coordination with other Pentagon officials. 'All calls from the Chairman to his counterparts, including those reported, are staffed, coordinated and communicated with the Department of Defense and the interagency. The Chairman of the Joint Chiefs regularly communicates with Chiefs of Defense across the world, including with China and Russia .

All calls from the Chairman to his counterparts, including those reported, are staffed, coordinated and communicated with the Department of Defense and the interagency. Also in keeping with his responsibilities as senior military advisor to the President and Secretary of Defense, General Milley frequently conducts meetings with uniformed leaders across the Services to ensure all leaders are aware of current issues. The meeting regarding nuclear weapons protocols was to remind uniformed leaders in the Pentagon of the long-established and robust procedures in light of media reporting on the subject. General Milley continues to act and advise within his authority in the lawful tradition of civilian control of the military and his oath to the Constitution.

'General Milley continues to act and advise within his authority in the lawful tradition of civilian control of the military and his oath to the Constitution.' The allegations that Milley broke the chain of command to make the 'secret calls' are part of 'Peril,' a book by Bob Woodward and Robert Costa. The account is set to hit shelves on September 21. It claims Milley made secret calls to his counterpart in Beijing while Trump was president. In it, the Washington Post journalists allege that he went behind Trump 's back to promise China to warn them if the U.S. planned to attack. Excerpts from 'Peril', which were published on Tuesday, detail that Milley sought to assure in calls with General Li Zuocheng of the People's Liberation Army in China that the U.S. was not about to launch strikes. In one call he said he would use backchannels to alert his counterpart if an attack were imminent. The details triggered a wave of condemnation from Republicans who accused Milley of treason. Alexander Vindman called on Joint Chiefs of Staff Mark Milley to resign if the claims are true. 'If this is true GEN Milley must resign,' the retired lieutenant colonel tweeted on Tuesday along with an article about new book 'Peril' which claims Milley was fearful Trump might spark war with China in the wake of his November election defeat to Joe Biden . 'He usurped civilian authority, broke Chain of Command, and violated the sacrosanct principle of civilian control over the military. It's an extremely dangerous precedent,' Vindman, the star witness in the first impeachment of President Trump, tweeted. 'You can't simply walk away from that.' Many are claiming Milley was wrong to circumvent the president, and are calling on Milley to step down from as top military officer. Retired Lieutenant Colonel Buzz Patterson, an aide during Bill Clinton's administration who protected the 'nuclear football,' said it was not Milley's job to make decisions in a civilian-controlled military. 'As a former carrier of the nuclear football, this is simply unconscionable,' Patterson tweeted. 'The military doesn't get to make this call in a civilian controlled system. Milley needs to resign immediately.' In a second tweet he wrote: I'm outraged and every veteran and active duty member should be too! Each and every one of us were educated and drilled to always respect the chain. The CJCS violated that and usurped the authority of the commander in chief for political purposes. He jeopardized our security.' Retired Lieutenant Colonel Alexander Vindman is demanding Chairman of Joint Chief of Staff Mark Milley resign if he did go behind President Trump's back to speak to China Retired Marine Colonel John Mee told DailyMail.com: 'If the reports are true, it's very disturbing. That completely flies in the face of civilian control of the military.' Mee, who worked for the Joint Staff as a division chief of NATO's policy division, continued: 'I think that would be unprecedented, to warn [secretly] of a pending attack.' Retired Colonel Rob Maness tweeted: 'If every veteran serving in the US Congress isn't calling Milley out and demanding his resignation and court martial, they deserve a primary opponent.' He also responded to Vindman's tweet in a separate post where he said: 'Resignation is not enough. 'These actions demand a public court martial proceeding.' Senator Marco Rubio wrote a letter to President Biden demanding that he fire Milley 'immediately' for working to 'actively undermine' Trump. The book's revelations triggered a wave of concern that Milley had violated the chain of command, endangering national security and breaking norms of civilian control of the military Retired Lieutenant Colonel Buzz Patterson, an aide during Bill Clinton's administration who protected the 'nuclear football,' said it was not Milley's job to make decisions in a civilian-controlled military Former Navy Lieutenant Adam Laxalt, who served as Attorney General of Nevada, said Milley's actions should be considered 'treason' '[Milley] worked to actively undermine the sitting Commander in Chief of the United States Armed Forces and contemplated a treasonous leak of classified information to the Chinese Communist Party in advance of a potential armed conflict with the People's Republic of China (PRC),' he wrote in the letter. 'These actions by General Milley demonstrate a clear lack of sound judgement, and I urge you to dismiss him immediately.' He added: 'General Milley has attempted to rationalize his reckless behavior by arguing that what he perceived as the military's judgement was more stable than its civilian commander. You must immediately dismiss General Milley. America's national security and ability to lead in the world are at stake.' Republican Louisiana Senator John Kennedy said Milley 'should resign' if he negotiated with his Chinese counterpart and undermined Trump. He told Fox Primetime host Lawrence Jones: 'You give me about 15 minutes with Gen. Milley under oath, in front of a committee of the United States Senate, and I will get to the truth.' 'If the truth is as alleged then, yes, he should resign.' On the other hand, former Navy senior chief petty officer and intelligence expert Malcolm Nance praised Milley for 'defending the Constitution' in bypassing the president to speak and make promises to a foreign adversary. 'My Take: #GeneralMilley is a true Patriot who defended the Constitution at its moment of greatest need,' Nance tweeted. 'He took steps to ensure no UNLAWFUL orders would be followed which could lead to national catastrophe by a mad man. He is a #Hero'. Republicans were furious over reports of Milley circumventing Trump to promise China he would warn them of any impending U.S. attack Retired Colonel Rob Maness aid 'resignation is not enough' and demanded a 'public court martial proceeding' Milley phoned his Chinese counterpart to give reassurances two days after the January 6 Capitol riot and cautioned US military leaders amid fears Trump might attack to keep power. Trump accused him of treason Fox News host Tucker Carlson slammed Milley as 'treasonous'. 'How do you describe this? 'Deep state' isn't strong enough. It's treason. It's a crime,' he said. 'To those who say they're worried about authoritarianism coming in America, well, it's here,' Carlson said. 'That's what this is. Authoritarian government. Government by unelected, unaccountable leaders willing to use violence to preserve their rule.' An angry Trump said Milley was 'making it up' that he was concerned about a China attack in an attempt to distract from his own role in the bungled Afghanistan withdrawal. 'I think he's trying to just get out of his incompetent withdrawal out of Afghanistan, the worst, the dumbest thing that anybody's seen,' Trump said. 'Probably the most embarrassing thing that's ever happened to our country.' The former president repeated his frequent condemnation of the Biden administration's handling of Afghanistan before returning the allegations in the new book, excerpts of which were published by CNN, the New York Times and the Washington Post . Trump said: 'Milley made it up. He made this story about me attacking China.' 'Think of it, I'm going to attack China. What's the reason exactly, other than that they screw a certain trade?' he continued. 'You don't attack them for that.' On the other hand, former Navy senior chief petty officer and intelligence expert Malcolm Nance praised Milley for 'defending the Constitution' in bypassing the president to speak and make promises to a foreign adversary He described Milley's alleged behavior as 'a disgrace.' 'He was going to inform them when that will take place so they could be prepared,' Trump said. 'That is a treasonous statement and I cannot tell you how many people called up about it.' Trump named Milley to the top military post in 2018, where he will serve until 2022. Their relationship, however, quickly soured and details of their clashes have seeped into public view with publication of several accounts of the final days of the Trump presidency. The upcoming book also detailed that Ivanka Trump told her father three times to stop pedaling election fraud claims as he watched the Capitol riot unfold on TV on January 6. 'Let this thing go,' Donald Trump's eldest daughter and then-senior adviser said at the time. 'Let it go.' The book 'Peril' also detailed that retired General Keith Kellogg, who was serving as Vice President Mike Pence 's national security adviser at the time, told Trump he should send a 'tweet' to help calm the crowd at the Capitol on January 6. 'You really should do a tweet,' Kellogg said, according to the book, written by journalist and author Bob Woodward and veteran Washington Post reporter Robert Costa. 'You need to get a tweet out real quick, help control the crowd up there,' he said as Trump watched the attack happening on television. 'This is out of control. They're not going to be able to control this. Sir, they're not prepared for it. Once a mob starts turning like that, you've lost it.' Ivanka Trump, pictured January 4, 2021 with Donald Trump, told her father on January 6 that he should 'let this thing go' as they watched the Capitol riot unfold, according to a new book The book also detailed that retired General Keith Kellogg told Trump he should send a 'tweet' to help calm the crowd at the Capitol on January 6 'Peril,' by Bob Woodward and Robert Costa will be released by Simon & Schuster on September 21 The then-president responded to Kellogg with a simple, 'Yeah' and then, the book details, 'Trump blinked and kept watching television.' The retired general, according to the book, was with Trump on January 6 while he watched the chaos unfold from the White House. The new book also revealed a bombshell that Chairman of the Joint Chiefs of Staff, General Mark Milley, called his Chinese counterpart twice last year over concerns President Trump was ready to go to war. Trump responded on Tuesday by saying the United States' top military officer was guilty of treason if he went behind his back with promises to warn China of an impending attack. 'If it is actually true – which is hard to believe that he would have called China, and done these things and was willing to advise them of an attack or in advance of an attack – that's treason,' Trump told Sean Spicer during an interview on Newsmax TV. The latest account details how Milley took a series of extraordinary actions after the Jan. 6th Capitol riot because he was concerned an 'unstable' President Trump might undertake military action in a desperate bid to stay in office. Milley met top military officials in the Pentagon two days after the MAGA riot and told them to keep him in the process for all military actions, including the use of nuclear weapons. 'If you get calls, no matter who they're from, there's a process here, there's a procedure. No matter what you are told, you do the procedure. You do the process. And I'm part of that procedure,' he told reportedly told them. He feared Trump was suffering 'serious mental decline,' according to the book, which relies on Woodward's well-established methods of relying on 'deep background' information provided sources, some of them anonymously, as well as documents and interviews, to attempt to reconstruct events and conversations.. 'The strict procedures are explicitly designed to avoid inadvertent mistakes or accident or nefarious, unintentional, illegal, immoral, unethical launching of the world's most dangerous weapons,' he continued. 'Got it?' Milley asked his team members. 'Yes, sir,' they replied, in an exchange Milley considered 'an oath.' Milley also told CIA Director Gina Haspel: 'Aggressively watch everything, 360.' Just as stunning were Milley's reported actions that same date to the head of China's powerful military, to reassure his counterpart that the US was not going to attack China and set off a clash with a major nuclear power. His message, despite his own doubts about Trump's mental state, was that 'everything's fine.' 'Things may look unsteady,' Milley told Gen. Li. 'But that's the nature of democracy, General Li. We are 100 percent steady. Everything's fine. But democracy can be sloppy sometimes.' US intelligence reportedly concluded the government of Chinese President Xi Jinping was concerned about a potential US attack after the Jan. 6 riot Milley called China's People's Liberation Army (PLA) General Li Zuocheng to provide reassurances over his alleged concerns Trump might take military action in a desperate move to retain power after his election loss It was Milley's second call to his counterpart in the final months of the Trump administration. US intelligence concluded the Chinese believed Trump might launch a military strike in order create a basis to stay in power, after an election Trump claimed was fraudulent, despite a series of court and procedural defeats that had him running out of options. Milley had earlier called Li in October amid ongoing tensions over the South China Straight, and Trump's rhetoric targeting China. Milley feared Trump might seek to use such an attack to achieve a Reichstag fire type incident, where he would cite the dangerous new situation to cling to power. Milley afterward concluded Li was 'unusually rattled.' According to the book, Milley even promised his counterpart there would be no surprises. They had reportedly established relations through a backchannel. 'General Li, you and I have known each other for now five years. If we're going to attack, I'm going to call you ahead of time. It's not going to be a surprise,' Milley reportedly told him. The book quotes Milley expressing concerns Trump might launch a strike that could lead to war. Trump campaigned repeatedly ending Middle East wars he called a waste, and negotiated a departure date with the Taliban in Afghanistan before leaving office. 'I continually reminded him, depending on where and what you strike, you could find yourself at war,' the book quotes Milley as saying of Trump. A president can only initiate a nuclear strike through a complex procedure that involves multiple layers of officials, coordinated through the National Military Command Center. Milley also spoke to House Speaker Nancy Pelosi, who had publicly raised her own fears about Trump's access to nuclear weapons immediately after the riot, which came on a day Congress met to count the electoral votes to make Joe Biden president. 'This is bad, but who knows what he might do?' Pelosi said. 'He's crazy. You know he's crazy. He's been crazy for a long time. So don't say you don't know what his state of mind is.' The authors cite a transcript of the call. Milley responded, according to the book: ' Madam Speaker. I agree with you on everything.' Pelosi told him: 'What I'm saying to you is that if they couldn't even stop him from an assault on the Capitol, who even knows what else he may do? And is there anybody in charge at the White House who was doing anything but kissing his fat butt all over this?' 'You know he's crazy. He's been crazy for a long time,' she told him. Milley's efforts to give himself the opportunity to potentially head off a strike or a war appears to have been triggered by his call with Pelosi. According to the transcript, she asked him 'what precautions are available to prevent an unstable president from initiating military hostilities or from accessing the launch codes and ordering a nuclear strike?' Milley then vouched for 'a lot of checks in the system.' Haspel had raised her own concerns after Trump refused to accept the results of the November election. 'We are on the way to a right-wing coup. The whole thing is insanity. He is acting out like a six-year-old with a tantrum,' she told him. 'This is a highly dangerous situation. We are going to lash out for his ego?' she told Milley in a call. The maneuvering came at a time after Milley had first accompanied Trump during his infamous photo-op shortly before authorities cleared protesters from Lafayette Square during Black Lives Matter protests in the summer of 2020. He then apologized for having participated in the event in uniform.
