WASHINGTON -- Demonstrators outside the U.S. Capitol, angry over the proposed health care bill, shouted "nigger" Saturday at U.S. Rep. John Lewis, a Georgia congressman and civil rights icon who was nearly beaten to death during an Alabama march in the 1960s.

Protesters also shouted obscenities at other members of the Congressional Black Caucus, spat on at least one black lawmaker and confronted an openly gay congressman with taunts.

Capitol Police escorted the members of Congress into the Capitol after the confrontation. At least one demonstrator was reported arrested.

"They were shouting, sort of harassing," Lewis said. "But, it's okay, I've faced this before. It reminded me of the 60s. It was a lot of downright hate and anger and people being downright mean."

Protesters also used a slur as they confronted Rep. Barney Frank, D-Mass., an openly gay member of Congress.

Frank told the Boston Globe that the incident happened as he was walking from the Longworth office building to the Rayburn office building, both a short distance from the Capitol. Frank said the crowd consisted of a couple of hundred of people and that they referred to him as 'homo.' A writer for The Huffington Post said the protesters called Frank a "faggot."
