WASHINGTON Federal authorities said Thursday that theyre working to hunt down the hundreds of insurrectionists who stormed the U.S. Capitol building in support of President Donald Trump , most of whom were allowed to leave without being arrested after laying siege to the seat of the United States government.

Acting Attorney General Jeffrey Rosen, who has headed the Justice Department since the departure of William Barr, said in a statement on Thursday that the DOJ is committed to ensuring that those responsible for this attack on our Government and the rule of law face the full consequences of their actions under the law.

FBI Director Christopher Wray said the attack showed a blatant and appalling disregard for our institutions of government and the orderly administration of the democratic process and that the FBI had deployed its full investigative resources to pursue those who committed crimes.

Make no mistake: With our partners, we will hold accountable those who participated in yesterdays siege of the Capitol, Wray said.

U.S. Attorney for the District of Columbia Michael Sherwin said that 40 defendants had been charged in D.C. Superior Court, while 15 defendants would face federal charges. He said one defendant had a military semi-automatic rifle and 11 Molotov cocktails that were ready to go.

According to Sherwin, the feds have a good start, but charges are just the beginning. Hundreds of federal officers are poring over video footage and social media, he said, and will also be using cell phone warrants to determine who, exactly, breached the Capitol and what they did.

They will be brought to justice, Sherwin said. They will be held accountable, both for what was done on the Capitol grounds and what happened within the Capitol.
