Who has been charged in riot?

Dozens of people have already been arrested and prosecutors across the United States have vowed to bring to justice those who stormed the U.S. Capitol on Wednesday, sending lawmakers into hiding.

The top federal prosecutor for the District of Columbia has said “all options are on the table” for charging the rioters, many of whom were egged on by President Donald Trump’s speech earlier in the day.

A Capitol Police officer died after he was hit in the head with a fire extinguisher and many other officers were injured.

A California woman was shot to death by Capitol Police and three others died after medical emergencies during the chaos.

Some questions and answers about the investigation into the Capitol breach:

How many people have been charged?

The U.S. attorney’s office for D.C. had filed 17 cases in federal court and at least 40 others in the Superior Court by Saturday. The cases in Superior Court mainly have to do with things like curfew violations and gun crimes. Those being tried in federal court are charged with things like violent entry and disorderly conduct on Capitol grounds, assaulting a federal law enforcement officer and threatening House Speaker Nancy Pelosi.

Defendants facing federal charges include Richard Barnett, the Arkansas man shown in a photo sitting in Pelosi’s office with his boots on the desk.

Another man being tried in federal court, Lonnie Coffman of Falkville, Ala., was arrested after authorities say they found guns and 11 Molotov cocktail explosive devices made out of Mason jars, golf tees and cloth rags in his pickup truck.

Why haven’t more people been charged?

Authorities said additional cases remained under seal and dozens of other people were being sought by federal agents.

U.S. attorneys in several states said people could face charges in their home states if they traveled to Washington and took part in the riot.

The FBI has released photos of people inside the Capitol, urging the public to help identify them.

Many people freely left the Capitol, which means investigators now have to work to identify them and track them down. Authorities have to distinguish between those who traveled to Washington to participate in the rally before the riot versus those who were part of the insurrection.

Could they face more serious charges?

Michael Sherwin, acting U.S. attorney for the District of Columbia, said that prosecutors are not keeping anything out of their “arsenal for potential charges.” As prosecutors gather more evidence, they can add more charges against those already arrested.

Could Trump be charged?

Trump urged the crowd to march on the Capitol and told his supporters to “fight” to stop the “steal” of the election.

But the legal bar for charging the president at the rally with inciting violence is high. Experts said it would be tough to prove that the president intended for violence to happen on Capitol Hill.
