The Department of Justice has charged more than 150 people and identified hundreds more as suspects in the violent assault on the U.S. Capitol by supporters of former President Donald Trump.

"We are committed to seeing this through no matter how many people it takes, how many days it takes us or the resources we ... need to get it done," said Steven D'Antuono, the assistant director in charge of the FBI's Washington Field Office.

Members of the insurrectionist mob that attacked the U.S. Capitol last week face what the federal prosecutor in charge calls a "mind-blowing" range of potential charges, from destruction of federal property, trespass and mail theft to possession of destructive devices and felony murder.

The acting U.S. attorney for the District of Columbia, Michael Sherwin, says "hundreds" of people may ultimately face charges related to the storming of the U.S. Capitol on Wednesday, which interrupted a session of Congress and left five people dead.

Sherwin spoke with NPR's Martin Kaste in an exclusive interview Saturday evening about the multiagency investigation, the challenges officials face and what they'll be looking for.
