Justice Department Warns It's Coming For Those Involved In Capitol Violence

Last week's storming of the U.S. Capitol by a pro-Trump mob has already resulted in charges against 70 people, according to the acting U.S. attorney for the District of Columbia, who said he expects the number "will grow into the hundreds."

In the first public briefing by the Justice Department and the FBI since Wednesday's riot, acting U.S. Attorney Michael Sherwin and Steven D'Antuono, director of the FBI's Washington Field Office, outlined what Sherwin called a long-term investigation.

"Everyone is in for the long haul," Sherwin said.

He said his office has already opened 170 subject files of people who potentially committed crimes in the Capitol or on Capitol grounds.
