What we know about the "unprecedented" Capitol riot arrests

America watched as hordes of rioters broke into the U.S. Capitol on January 6 — crushing through windows, pressing up stairways, and sending lawmakers and law enforcement running for their lives. The flood of protesters who streamed into the Capitol that day left federal authorities with an equally immense task: finding and charging those responsible.

In an interview with "60 Minutes," Michael Sherwin, a federal prosecutor who led the criminal investigation until March 19, said, "we're over 400 criminal cases." Prosecutors have called the case "unprecedented" in scale, and the government said in a court filing March 12, "The Capitol Attack is likely the most complex investigation ever prosecuted by the Department of Justice."
