The investigation and resulting report from Reps. Jim Banks (R-IN), Jim Jordan (R-OH), Troy Nehls (R-TX), Kelly Armstrong (R-ND), and Rodney Davis (R-IL) found that "leadership and law enforcement failures within the U.S. Capitol left the complex vulnerable on January 6, 2021" yet the "Democrat-led investigation in the House of Representatives, however, has disregarded those institutional failings that exposed the Capitol to violence that day."
All five members who conducted the investigation were put forward by House GOP Leader Kevin McCarthy to represent Republicans on Pelosi's select committee. But Pelosi rejected Reps. Banks and Jordan, at which point the other three members also withdrew from participating in the committee.
