A Capitol rioter was sentenced to 8 months in prison on Monday, the first felony sentence imposed on a participant in the attack on Jan. 6.

Paul Allard Hodgkins had pleaded guilty to one count of obstruction of an official proceeding, which carries a maximum possible sentence of 20 years in prison.

U.S. District Court Judge Randolph Moss ordered the sentence in a hearing, saying he was encouraged by Hodgkins’s remorse over his participation in the riot, but called the events on Jan. 6 “chilling.”
