From Sam Stein at the Huffington Post:
Abusive, derogatory and even racist behavior directed at House Democrats by Tea Party protesters on Saturday left several lawmakers in shock.
Preceding the president’s speech to a gathering of House Democrats, thousands of protesters descended around the Capitol to protest the passage of health care reform. The gathering quickly turned into abusive heckling, as members of Congress passing through Longworth House office building were subjected to epithets and even mild physical abuse.
A staffer for Rep. James Clyburn (D-S.C.) told reporters that Rep. Emanuel Cleaver (D-Mo.) had been spat on by a protestor. Rep. John Lewis (D-Ga.), a hero of the civil rights movement, was called a ‘ni–er.’ And Rep. Barney Frank (D-Mass.) was called a "faggot," as protestors shouted at him with deliberately lisp-y screams. Frank, approached in the halls after the president’s speech, shrugged off the incident.
But Clyburn was downright incredulous, saying he had not witnessed such treatment since he was leading civil rights protests in South Carolina in the 1960s.
