The hearing is set to start at 10 a.m. ET. The committee has not yet announced any witnesses.
While the committee did not announce the hearing’s topic in its notice, Democratic Rep. Adam Schiff of California, a member of the committee, had previously told CBS’ “Face the Nation” over the past weekend that the next hearing will focus on “efforts to assemble that mob on the mall” and connections between the Trump White House and various extremist groups at the rally that preceded the attack on the US Capitol, including the Proud Boys, Three Percenters and others.
Kinzinger said on “State of the Union” that he didn’t want to “get into who or any of those details” about potential new witnesses, but noted that “every day we get new people that come forward” to the committee.
