In an interview, Brock confirmed that he was the man in the photos and videos. He denied that he held racist views and echoed Trump’s baseless claims of election fraud, saying that he derived his understanding of the matter principally from social media. He told me that he had gone to Washington, D.C., to demonstrate peacefully. “The President asked for his supporters to be there to attend, and I felt like it was important, because of how much I love this country, to actually be there,” he said. Brock added that he did not identify as part of any organized group and claimed that, despite the scenes of destruction that day, he had seen no violence. When he arrived at the Capitol, he said, he assumed he was welcome to enter the building.

Brock denied that he had entered Pelosi’s office suite, saying that he “stopped five to ten feet ahead of the sign” bearing her title that insurrectionists later tore down and brandished. However, in the ITV video, he appears to emerge from the suite. Brock said that he had worn tactical gear because “I didn’t want to get stabbed or hurt,” citing “B.L.M. and Antifa” as potential aggressors. He claimed that he had found the zip-tie handcuffs on the floor. “I wish I had not picked those up,” he told me. “My thought process there was I would pick them up and give them to an officer when I see one. . . . I didn’t do that because I had put them in my coat, and I honestly forgot about them.” He also said that he was opposed to vandalizing the building, and was dismayed when he learned of the extent of the destruction. “I know it looks menacing,” he told me. “That was not my intent.”
