As more people are charged in connection with the attack, it has become clear that many of those who went to Washington last week were not only angry but heavily armed and, in some cases, dangerous. That point was driven home by court papers filed on Wednesday in the case of Cleveland G. Meredith Jr., who wrote in a text message that he wanted to put a bullet in the “noggin” of Speaker Nancy Pelosi on “live TV,” prosecutors said.
According to the papers, Mr. Meredith drove across the country with a Tavor X95 assault rifle, a 9 mm pistol painted to resemble an American flag and about 2,500 rounds of ammunition, including at least 320 armor-piercing 5.56 caliber rounds. Prosecutors say Mr. Meredith, who has a history of drug abuse and mental illness, also threatened to kill Mayor Muriel E. Bowser of Washington.
“I may wander over to the Mayor’s office and put a 5.56 in her skull,” he wrote in a text message, the court papers said.
This mood of outrage found an echo in the tumultuous congressional debate on impeachment, which stretched throughout the day. The sense of recrimination went beyond the boundaries of Washington as local politicians in other states lobbed accusations at each other.
A group of Arizona state lawmakers released a letter on Wednesday that they had sent a day earlier to Mr. Rosen and Mr. Wray, calling for an investigation into two of their own colleagues, Mark Finchem and Anthony Kern, who, according to social media posts, were at the riot at the Capitol.
The lawmakers also mentioned that two congressmen from Arizona, Paul Gosar and Andy Biggs, both Republicans, had planned the rally that preceded the riot with the organizer of the so-called Stop the Steal movement, Ali Alexander. A spokesman for Mr. Biggs has denied that he had any role in organizing the rally. Mr. Gosar appeared to be on friendly terms with Mr. Alexander, frequently tagging him in Twitter posts. At a rally last month outside the Arizona State Capitol at which Mr. Gosar spoke, Mr. Alexander called the congressman “the spirit animal of this movement.”
