Watching the speech I felt he’s working for a better deal for workers. But then this:

O’Brien rejected criticism of his appearance at the convention.

He said: “I don’t care about getting criticized. Its an honor to be the first Teamster in our 121-year history to address the Republican national convention. Think about this. The Teamsters are doing something correct if the extremes in both parties think I shouldn’t be on this stage,” he continued.

Sounds sus.
