WATCH LIVE: Jan. 6 Committee hearings - Day 4

Warning: This hearing may include footage of violence and strong language.

The House committee investigating the Jan. 6 attack will hold its fourth public hearing June 21, focused on former President Donald Trump's efforts to pressure state legislators and local election officials to change the results of the 2020 presidential election.

The hearing is scheduled to begin at 1 p.m. ET on Tuesday, June 21.

The hearing comes after the committee on Thursday, June 16 laid out evidence on how Trump pressured his then- vice president, Mike Pence, to overturn the election, even as the Capitol insurrection was underway. The June 16 hearing played out testimony from several aides and close Trump allies that all testified to the pressure that the president was putting on Pence. The vice president is charged with overseeing the Electoral College vote count -- already certified by individual states -- in a joint session of Congress following a presidential election-- that is what was taking place on Jan. 6, 2021. Pence said on that day that he did not have the constitutional authority to do what the president had asked.

Members of the committee said last week they thought they had evidence to indict Trump for seeking to overturn the results of the 2020 election, which they will lay out as part of several public hearings this month.
