To the best of my knowledge, Trumka did not oppose Hillary’s plan to shut down the mines and throw the miners out of work. He also doesn’t have appeared to have spoken out strongly against the outsourcing of jobs to China. A strong union leader, dedicated to the welfare of his members, would have gone to verbal war with these threats to his members.
Kind of depended which network he was being interviewed on. I would see him a decent amount on CNBC and he took on a more moderate tone there.
