On Wednesday (Jan. 6), armed supporters of President Donald Trump forced their way into the U.S. Capitol in Washington, D.C., waving Confederate and pro-Trump flags as they stormed the steps and breached the building. Shortly before the rioters broke into the Capitol, President Trump spoke at a rally saying “we will never concede,” referring to the election that he lost to President-elect Joe Biden by more than 7 million votes, The New York Times reported. Trump also encouraged his followers to march on the Capitol, according to The Times.

President-elect Biden said in a statement: “This is not dissent. It’s disorder, it’s chaos, it borders on sedition.” But what exactly is sedition? The term describes acts or words encouraging insurrection against the government.
