“Those members of Congress who had groups coming through the Capitol that I saw on Jan. 5, a reconnaissance for the next day, those members of Congress that incited this violent crowd,” Ms. Sherrill said, “those members who attempted to help our president undermine our democracy, I’m going to see that they’re held accountable.”
On Wednesday, about 30 lawmakers joined Ms. Sherrill in requesting an investigation from the acting House and Senate sergeants-at-arms and the Capitol Police into what Ms. Sherrill called “suspicious behavior” and access given to visitors to the Capitol complex the day before the riot.
“Many of the members who signed this letter, including those of us who have served in the military and are trained to recognize suspicious activity, as well as various members of our staff, witnessed an extremely high number of outside groups in the complex on Tuesday, January 5,” the lawmakers wrote. They called the visits suspicious, noting that tours have been restricted because of the coronavirus pandemic.
Representative Tim Ryan, Democrat of Ohio, said lawmakers were aware of the tours but are now looking at them in a new light given the attack. He said they included “handfuls” of people and that the authorities were aware of them. “Now you look back on certain things and you look at them differently so, yeah, we’re looking into it,” he said.
Mr. Crow said he was aware of tours but uncertain about their nature.
Pressure is mounting on the Republican members of Congress who associated themselves with far-right extremist groups in the days leading up to the mob attack. Several of Mr. Trump’s most ardent supporters, including Representatives Mo Brooks of Alabama and Paul Gosar and Andy Biggs, both of Arizona, have been accused of helping plan the Jan. 6 rally that led to the violent attack on the Capitol.
A photo also circulated misleadingly online on Wednesday that purported to implicate Representative Lauren Boebert of Colorado in giving such a tour, but it was from 2019 in Colorado.
Mr. Crow said he found the photograph concerning nonetheless because others in it flashed “white power gang symbols.”
