According to the congressional committee looking into his supporters’ assault on the U.S. Capitol last year, former President Donald Trump did not appear for his deposition hearing.

In doing so, Chair Bennie Thompson, a Democrat, and co-Chair Liz Cheney, a Republican, alleged that Trump disobeyed a subpoena issued by the panel in October.

The truth is that Donald Trump is avoiding the Select Committee’s investigation, like a number of his closest allies, and refusing to comply with what more than a thousand other witnesses have done, according to Thompson and Cheney.

The panel did not say what next steps they might pursue against Trump. Thompson told the New York Times in an interview that he would not rule out seeking contempt of Congress charges against the former president.

“That could be an option. And we’ll have to wait and see,” Thomson told the Times. “The first thing we’ll do is see how we address the lawsuit. At some point after that, we’ll decide the path forward.”

Trump filed a lawsuit on Friday seeking to avoid having to testify or provide any documentation to the Jan. 6 committee.

In an effort to convince the public that Trump incited his followers to assault the U.S. Capitol on January 6, 2021, as lawmakers gathered to officially pronounce his loss to Democrat Joe Biden, the congressional committee has convened a number of hearings.

Trump was required by the subpoena to provide the panel with materials by November 4 and to present for deposition testimony starting on or around November 14.

On November 4, it declared that it had agreed to grant Trump a delay before releasing the records, but the deadline of November 14 remained in effect.

Republicans are expected to dissolve the panel if they win control of the U.S. House of Representatives in the mid-term elections.
