WASHINGTON — A federal judge sentenced the founder of the far-right militant Oath Keepers Stewart Rhodes to 18 years in prison on Thursday for seditious conspiracy and other crimes related to the U.S. Capitol attack, after a defiant Rhodes stood before him and insisted he is a “political prisoner.”

“For decades, Mr. Rhodes, it is clear you have wanted the democracy of this country to devolve into violence,” U.S. District Judge Amit Mehta said.
