House Speaker Nancy Pelosi on Monday introduced a bill to establish a committee to investigate the Jan. 6 attack at the U.S. Capitol that’s heavily weighted towards Democrats after Senate Republicans scuttled a bipartisan deal last month.

“The Select Committee will investigate and report upon the facts and causes of the attack and report recommendations for preventing any future assault,” Pelosi, D-Calif., said in a statement after the bill was introduced.

“January 6th was one of the darkest days in our nation’s history. It is imperative that we establish the truth of that day and ensure such an attack cannot again happen,” she said.

The bill, which was expected to go to the Rules Committee on Monday night and then the House floor on Wednesday, puts Pelosi firmly in control of the process. Asked whether she thinks any Republican members would vote in support of the bill, Pelosi said, “I have no idea. Ask them.”

“The Speaker shall appoint 13 Members to the Select Committee, 5 of whom shall be appointed after consultation with the minority leader,” the bill says.
