Trump has sought to appeal to working-class voters through promises of job creation and the renegotiation of trade deals, among other things.

But Clinton noted some of Trump’s anti-union positions and accused the real estate magnate of building his wealth by “stiffing small businesses and contractors.”

“If you do know somebody who might be voting for Trump, stage an intervention,” Clinton pleaded with her remote audience. “Try to talk some sense into them. Lay out the facts. The facts are on our side, about what I’ve done versus what he’s done. Remember, friends don’t let friends vote for Trump.”
