The House committee investigating the Jan. 6, 2021 insurrection released video on Wednesday of a Capitol tour led by a Republican lawmaker the day before the attack, showing participants taking photos of stairwells and tunnels in the complex.

The panel released the video as it renewed calls for the GOP lawmaker, Georgia Rep. Barry Loudermilk, to speak to the committee about the tour. Loudermilk has so far declined the interview and denied any wrongdoing, and the chief of the U.S. Capitol Police said in a letter to Republicans this week that after reviewing surveillance video, “we do not consider any of the activities we observed as suspicious.”

Still, the committee says it has questions. In addition to the surveillance video, the footage released by the panel also includes video of an unidentified man walking toward the Capitol on Jan. 6 holding a flagpole that appears to have a sharpened end, which he says is “for a certain person.” The committee says the man in the video is one of the tour participants who was taking photos inside the Capitol the day before.

Later footage shows the man near the Capitol and making apparent threats toward Democrats, including House Speaker Nancy Pelosi, Senate Democratic Leader Chuck Schumer and New York Reps. Jerrold Nadler and Alexandria Ocasio-Cortez.

“They’re coming in, coming in like white on rice for Pelosi, Nadler, even you, AOC,” the man says in the video released by the committee. “We’re coming to take you out and pull you out by your hairs. … When I get done with you, you’re going to need a shine on top of that bald head.”

The panel did not say whether he got into the Capitol or whether he had faced any charges. While more than 800 people have been charged for breaking into the building, or for violently beating police officers, thousands of other protesters were outside the building or on the National Mall and did not engage in violence. The breach temporarily halted the certification of President Joe Biden’s victory.

In a Wednesday letter to Loudermilk renewing the request for an interview, Mississippi Rep. Bennie Thompson, the committee’s chairman, said the panel “had hoped to show you the video evidence when you met with us” but was releasing it publicly because Loudermilk had so far declined. Thompson said the areas photographed and recorded by some on the tour are “not typically of interest to tourists, including hallways, staircases, and security checkpoints.”

Another member of the panel, Republican Rep. Adam Kinzinger of Illinois, tweeted after the video was released: “Please take a look. These are not normal tour routes, the Capitol was closed to tours.”

The back-and-forth with Loudermilk has underscored the committee’s difficulty in getting any information from Republicans who were communicating with President Donald Trump, the White House or the rioters during the insurrection or beforehand as Trump strategized about how to overturn his election defeat. While the panel has conducted more than 1,000 interviews, five GOP lawmakers have defied subpoenas, including House GOP Leader Kevin McCarthy, who spoke with Trump that day.

Loudermilk has not been subpoenaed, and there is no evidence that he knew that any of the participants on his tour were outside the Capitol the next day.
