Congress spokesperson P C Chacko said the incident was "totally unacceptable".
"American society's plus point or their great achievement, as they always claim, is that they are a pluralist and inclusive society. So this is totally unacceptable what happened there.
"If the Government of the United States cannot protect other communities, especially the Indian communities there, then they have no right to speak about such things happening in other countries," Chacko said.
