The House Select Committee is asking Republican Rep. Scott Perry to turn over all his communications with former President Trump. The move is a distinct change from previous requests from the House panel which has repeatedly resorted to issuing subpoenas to allies of President Trump.

The Hill reports:

The move follows prior reports that found Perry, the incoming chairman of the far-right Freedom Caucus, to be a central figure in former President Trump’s efforts to pressure the Department of Justice to act on his baseless claims of election fraud. That includes introducing the president to Jeffrey Clark, a midlevel Justice Department employee that Trump once weighed installing as attorney general.

Perry’s role in Trump’s pressure campaign at the Justice Department came to light following a Senate Judiciary Committee investigation into Trump’s plans to boot acting Attorney General Jeffrey Rosen, putting Clark in a better position to forward voting investigations in states where Trump lost. But the upheaval was stalled when several high-level Justice Department figures threatened to resign at a Jan. 3 White House meeting.

The letter asked that Rep. Perry voluntarily turn over all communication with the former President and his legal team.

“We have received evidence from multiple witnesses that you had an important role in the efforts to install Mr. Clark as acting Attorney General.  Acting Attorney General Rosen and acting Deputy Attorney General Donoghue have provided evidence regarding these issues, and we have received evidence that others who worked with Mr. Clark were aware of these plans,” Rep. Bennie Thompson (D-Miss.), the chairman of the panel, wrote in a letter to Perry.

“We are also aware that you had multiple text and other communications with President Trump’s former Chief of Staff regarding Mr. Clark — and we also have evidence indicating that in that time frame you sent communications to the former Chief of Staff using the encrypted Signal app,” Thompson wrote.
