Oath Keepers founder sentenced to 18 years in prison for plot to keep Donald Trump in power. He is the first defendant convicted of seditious conspiracy to receive a final sentence.

Prosecutors say he remains a threat to American democracy more than two years after the plot. Three of his co-defendants were acquitted of sedition but convicted of other crimes. They were found guilty of a lesser charge of conspiracy to commit a felony. The other three were found not guilty of the lesser charge.
