Donald Trump's former acting Secretary of Defense, Chris Miller, has revealed that he felt "threatened" by former Congresswoman Liz Cheney and other members of the January 6th Committee after he refused to endorse their version of events.

In an interview with Daily Mail, Miller said that he became "fearful" of the panel's tactics after they tried to stop him making claims that ran contrary to their preferred narrative.

According to Miller, the panel were particularly upset by a Fox News interview he gave with Trump national security official Kash Patel in which he pointed out that the former president authorized the National Guard to step in quell the protests taking place in and around the Capitol.

"The two of us were on [the Fox News show] and the next day my lawyer got a call from the Jan. 6 staff director – I forgot exactly who it was – but basically saying, very legalistic: 'Well, if your client has additional information he wants to share, we'd be happy to have him re-interviewed,'" Miller explained.

"It was more that latent threat of: 'If you want to keep going on TV, we're gonna drag you in here again for additional hours of hearing testimony.' So that was the nature of that whole thing,'" he continued.

He also outlined his view that the Committee's Vice Chair Liz Cheney was the person "running the show" and that she was concerned about the "optics" of his claims that Trump attempted to restore order.

Miller, who was appointed as acting Secretary of Defense in October after his precedessor refused to act on evidence of widespread election fraud, added that he had not wanted to publicly discuss his concerns until now.
