US President Donald Trump said his predecessor’s 11th-hour pardons of members of Congress who investigated the January 6 insurrection were “void, vacant and of no further force or effect,” signaling his administration may attempt to upend more than a century of law and practice for presidential pardons.

President Donald Trump has said that Joe Biden's 11th-hour pardons of members of Congress who investigated the January 6 attack are "void, vacant and of no further effect."

In a post on Truth Social, Trump said that the pardons issued by his predecessor are not valid because they were allegedly signed using an autopen—a device that replicates a person's signature.

Trump also warned members of the former January 6 House select committee that they would now be "subject to investigation at the highest level."

Donald Trump declared his predecessor's last-minute pardons 'void, vacant and of no further force or effect' as he warned that members of the House committee investigating the January 6 riots can now face prosecution.

Trump claimed late Sunday night that because Joe Biden used an autopen the pardons cannot be enforced and even made the stunning suggestion they were signed without the former president's knowledge. 

Former Rep. Liz Cheney is facing calls from GOP legislators that the FBI investigate her for "potential criminal witness tampering" related to her former role on the Jan. 6 House Select Committee, according to a report released Tuesday by House Administration Subcommittee on Oversight Chair Rep. Barry Loudermilk, R-Ga.

Wrapping up their own investigation on the Jan. 6 2021 Capitol attack, House Republicans have concluded it’s former GOP Rep. Liz Cheney who should be prosecuted for probing what happened when then-President Donald Trump sent his mob of supporters as Congress was certifying the 2020 election.

The findings issued Tuesday show the Republican Party working to reinforce Trump’s desire to punish his perceived enemies including Cheney and members of the Jan. 6 committee that the president-elect has said should be in jail.

Republicans released a report Tuesday reviewing the “failures and politicization” of the now-disbanded House Jan. 6 committee, capping their investigation by recommending a criminal investigation into former Rep. Liz Cheney (R-Wyo.).

The 128-page interim report forwards many of the claims circulated by the GOP since the committee was organized, complaining the Jan. 6 select committee was improperly constituted and unfairly pinned blame on President-elect Trump.

A federal judge on Thursday told Stephen K. Bannon, a longtime adviser to former President Donald J. Trump, to surrender by July 1 to start serving a four-month prison term imposed on him for disobeying a subpoena to give testimony to the House committee that investigated the Jan. 6, 2021, attack on the Capitol.
