With a growing number of arrests and charges related to last week's storming of the U.S. Capitol, multiple law enforcement agencies are building a sprawling investigation into who participated in the violence that claimed at least five lives and sent fearful lawmakers into hiding. Nearly 100 people have been arrested for their roles in the attack carried out by thousands of President Donald Trump’s supporters or in unrest surrounding the Capitol that day. Many face lesser charges such as unlawful entry, disorderly conduct and defacing public property. Only a few have been accused of more serious crimes, such as felony violations of the Riot Act.
