If you can't trust a union boss, who can you trust?

So: Trumka personally witnessed these events, which somehow a throng of people with video cameras all missed. And he can prove he was there. And it only took him three weeks to speak up about it, when directly asked by a guy who’s offering a $100,000 reward for any evidence.

And of course, Trumka has no reason to lie. No reason at all to try to discredit these folks.

What more proof do you need?
