James Hoffa, general president of the International Brotherhood of Teamsters, had some choice words for the tea party on Labor Day.

"Let's take these son-of-a-bitches out and give America back to America where we belong," he said onstage in Detroit while warming up the crowd for President Obama, who spoke at the same event.

Tea partiers have not taken kindly to his comment.

After criticizing Hoffa in a statement to press, Tea Party Express blasted out a fundraising email hitting Obama for failing to reject Hoffa's sentiment:

It is disgusting and shameful that Obama allows this kind of violent rhetoric to continue. Isn't he the President of ALL Americans? How dare he allow his supporters to "declare war" on American people who are standing up for liberty? The reason President Obama doesn't put an end to the onslaught of attacks and insults is simple... he agrees with them.

Tea Party Nation founder Judson Phillips, meanwhile, wrote on his group's website, "Oops, someone else missed the message on civility. Where is the media on this? Where is Obama on this?"

Presidential candidate Herman Cain took aim at Hoffa in a Fox News interview, suggesting Hoffa and Obama have sought to intimidate tea partiers. Pressed by Fox host Gretchen Carlson to condemn Hoffa, Democratic National Committee Chairwoman Debbie Wasserman Schultz accused the network of overlooking heated rhetoric deployed by tea partiers.
