Former President Donald Trump has been indicted over his attempt to remain in power after he lost the 2020 presidential election, yet another moment of reckoning amid a torrent of criminal charges.

Trump faces four felony charges as part of a sweeping, 45-page indictment filed in the U.S. District Court for the District of Columbia. Special counsel Jack Smiths team of investigators accused the former president of multiple conspiracies to defraud the United States, to obstruct an official proceeding and to deprive people of their right to vote and have that vote counted under the Constitution.

Here are seven key things to know.

1. Trump knew his claims were false but spread them anyway to create an intense national atmosphere of mistrust and anger.

Prosecutors note that Trump, like every American, had the right to speak publicly about the election and even to claim, falsely, that there had been outcome-determinative fraud.

But his efforts became unlawful when he moved to defraud the United States and attempt to subvert the process of collecting, counting and certifying the election results. That plan, the indictment says, included a multi-prong approach to spread lies, install slates of fake electors in swing states and convince election officials and then-Vice President Mike Pence to subvert the will of the people.

Despite having lost, the Defendant was determined to remain in power, the indictment says.
