Despite hundreds of charges already brought in the year since pro-Trump rioters stormed the Capitol in an effort to stop the certification of President Joe Biden's 2020 election victory, these were the first seditious conspiracy charges levied in connection with the attack on Jan. 6, 2021.

It marked a serious escalation in the largest investigation in the Justice Department's history – more than 700 people have been arrested and charged with federal crimes – and highlighted the work that has gone into piecing together the most complicated cases. The charges rebut, in part, the growing chorus of Republican lawmakers who have publicly challenged the seriousness of the insurrection, arguing that since no one had been charged yet with sedition or treason, it could not have been so violent.

The indictment alleges Oath Keepers for weeks discussed trying to overturnthe election results and preparing for a siege by purchasing weapons and setting up battle plans. They repeatedly wrote in chats about the prospect of violence and the need, as Rhodes allegedly wrote in one text, "to scare the s—-out of" Congress. And on Jan. 6, the indictment alleges, they entered the Capitol building with the large crowds of rioters who stormed past police barriers and smashed windows, injuring dozens of officers and sending lawmakers running.
