President Biden took aim at former President Trump during a campaign event in Pennsylvania Saturday, using his remarks to portray his predecessor as an anti-union leader who, if re-elected, would roll back some of the union’s hardest-won gains.

Speaking at an event in Pittsburgh, Biden repeatedly described Trump as a “loser” who doesn’t care about union workers and would be happy to do so. remove benefits like health care and pension plans if he wins the presidency a second time.

“Donald Trump is a loser,” Biden told the audience. “He’s a losing candidate – and he’s a losing man.”

“I’ve never been more direct,” Biden added. “But I tell you, (Trump) is all about making sure you bring people down. He thinks the way to get ahead is to push people down.”
