Protesters with the Occupy D.C. and Stop The Machine movements will try to shut down the Senate Hart Building at 11:30 a.m today.
Protesters were gathering in the atrium of the building as Capitol police officers loomed nearby and as other demonstrators in anti-war gear set themselves up in the lobbies of floors overlooking the lobby.
The protestors made their way from Freedom Plaza, where they've set up camp, to Capitol Hill in small groups, trying to avoid a "march" down Pennsylvania Ave.
"Is the Hart building, how do I get to the Hart building? Am I in it?" one protester asked a a Hill staffer.
We'll have updates as the situation develops.Late update:
There were a handful of arrests
during the demonstration, which was organized by Stop The Machine and October 2011 protestors but was joined by people who said they were affiliated with the Occupy D.C. movement.
