WASHINGTON - US Senate Republican leader Mitch McConnell said on Wednesday that 'messages of hate and bigotry' from white supremacists, the Ku Klux Klan and neo-Nazi groups should not be welcome anywhere in the United States. 'We can have no tolerance for an ideology of racial hatred. There are no good neo-Nazis, and those who espouse their views are not supporters of American ideals and freedoms. We all have a responsibility to stand against hate and violence, wherever it raises its evil head,' McConnell said in a statement.
