U.S. Capitol Police arrested an anti-abortion rights protester outside the Capitol building on Monday morning.

The man, 44-year-old Rives Grogan of California, was apprehended and charged with disorderly conduct at around 10:10 a.m. Grogan was spotted by The Hill sitting approximately 10 feet in front of an entrance to the Senate near Constitution Ave., NE. The Capitol Police confirmed the arrest Monday afternoon.

Several officers stood behind Grogan as he chanted anti-abortion slogans. Grogan was alone at the time of his arrest.

The arrest comes on a day when Sen. Ben Nelson (D-Neb.) unveiled his amendment intended to prevent federal funds from paying for abortions. The measure, which is not expected to pass, is supported by anti-abortion rights senators but is opposed by senators who support abortion rights.
