Former Acting Attorney General Testifies About Trump’s Efforts to Subvert Election

He also discovered that Mr. Clark had been engaging in unauthorized conversations with Mr. Trump about ways to have the Justice Department publicly cast doubt on President Biden’s victory, particularly in battleground states that Mr. Trump was fixated on, like Georgia. Mr. Clark drafted a letter that he asked Mr. Rosen to send to Georgia state legislators, wrongly asserting that they should void Mr. Biden’s victory because the Justice Department was investigating accusations of voter fraud in the state.

Such a letter would effectively undermine efforts by Mr. Clark’s colleagues to prevent the White House from overturning the election results, and Mr. Rosen and his top deputy, Richard P. Donoghue, rejected the proposal.

Senator Richard Blumenthal, Democrat of Connecticut, said Mr. Rosen discussed previously reported episodes, including his interactions with Mr. Clark, with the Senate Judiciary Committee. He called Mr. Rosen’s account “dramatic evidence of how intent Trump was in overthrowing the election.”

Mr. Blumenthal was one of a handful of senators, including Thom Tillis, Republican of North Carolina, and Sheldon Whitehouse, Democrat of Rhode Island, who sat through most of Mr. Rosen’s more than six hours of testimony. Richard J. Durbin, Democrat of Illinois and chairman of the committee; Charles E. Grassley, Republican of Iowa; Amy Klobuchar, Democrat of Minnesota; Ben Sasse, Republican of Nebraska; and Mike Lee, Republican of Utah, attended parts of the interview.

Mr. Blumenthal said Mr. Rosen presented new facts and evidence that led him to believe that the committee would need to answer “profound and important questions” about the roles that individuals in Mr. Trump’s orbit played in the effort to undermine the peaceful transition of power, “which is what Trump tried to do, intently and concertedly.”

As details of Mr. Clark’s actions emerge, it is unclear what, if any, consequences he could face. The Justice Department’s inspector general could make a determination about whether Mr. Clark crossed the line into potentially criminal behavior. In that case, the inspector general could refer the matter to federal prosecutors.
