WASHINGTON (AP) — An eastern Missouri man pleaded guilty Monday to participating in the Jan. 6 riot at the U.S. Capitol.

Paul S. Westover, 53, of Lake St. Louis, pleaded guilty to a misdemeanor charge of parading, demonstrating or picketing in a Capitol building. In exchange for his plea, one felony charge and three other misdemeanors were dismissed, The Kansas City Star reported.

Westover will be sentenced Feb. 16. He faces a maximum penalty of six months in prison, a $5,000 fine and five years' probation. He also must pay $500 in restitution for damage to the Capitol building,

Seventeen Missouri residents have been charged with participating in the riot, and five have now pleaded guilty.
