U.S. Capitol and D.C. Police will be the first to testify before a new House committee created to investigate the Jan. 6 riot at the Capitol.

Four officers will testify about their first-hand experiences during the attack, when hundreds of angry protesters pushed their way past metal gates and overwhelmed law enforcement before storming into the building while both the House and Senate were in session.

The hearing is slated for July 27, and so far, only Democratic appointees are seated on the committee.

Republicans can appoint five lawmakers in consultation with Speaker Nancy Pelosi, a California Democrat.

Minority Leader Kevin McCarthy, a California Republican, has not chosen any lawmakers yet or indicated whether he’ll ever fill the seats.

Pelosi appointed Republican Liz Cheney of Wyoming to fill one of the eight seats controlled by Democrats.

Cheney is among a group of Republicans who publicly blame former President Donald Trump for inciting the riot by declaring the 2020 election rigged in Joe Biden’s favor.

The rioters stormed the Capitol to protest lawmakers certifying the election in Biden’s favor.

The July 27 witness list includes Harry Dunn, a Capitol Police officer who described police being overrun by violent protesters who also attacked him with racial slurs.

D.C. Police officer Michael Fanone will also testify. Fanone was injured during the riot and has called on McCarthy to “denounce” the 21 Republicans who voted against awarding the police the Congressional Gold Medal for their actions during the riot.

Both Fanone and Dunn met privately with McCarthy to complain about the GOP response to the riot. Some Republicans disagree with Democrats labeling the event an insurrection, while Democrats say the GOP is downplaying the incident.
