Jan. 6 committee member Rep. Adam Schiff is presenting additional findings during the panel's fourth hearing this month.
CNN previously reported that Schiff was expected to play a leading role in Tuesday's hearing.
Schiff is a Democrat from California and serves as chairman of the House Permanent Select Committee on Intelligence.
He was the lead impeachment manager representing Democrats during former President Trump's first impeachment trial.
"January 6 will be remembered as one of the darkest days in our nation's history. Yet, more than a year later, the threat to our democracy is as grave as ever. January 6 was not a day in isolation, but the violent culmination of multiple efforts to overturn the last presidential election and interfere with the peaceful transfer of power for the first time in our history," Schiff said in a statement to CNN.
"The former President and his allies have spent every day since January 6 attempting to rewrite history about that bloody attack on our nation's Capitol. That's why these public hearings are so essential — to show the American people exactly how January 6 came about, who is responsible, and most critically, what we can and must do to prevent another attack on our democracy."
