Sean O'Brien, the president of the Teamsters union, will speak at the Republican national convention in Milwaukee next month, a move that could spell trouble for Joe Biden's support among blue-collar workers ahead of the November election.

Donald Trump, the presumptive Republican nominee, announced on Friday on his Truth Social platform that O'Brien had accepted his invitation to speak at the convention and that he was looking forward to seeing him represent the Teamsters.
