Vice President Joe Biden on Tuesday questioned Donald Trump's "moral center" as a result of the Republican presidential candidate's comments about America's housing collapse.
Biden told a Hillary Clinton rally at Drexel University in Philadelphia on Tuesday that Trump had bragged at Monday's presidential debate about profiting from the failed housing market.
The vice president said Trump "is a guy who said it was good business for him to see the housing market fail."
Biden added, "What in the hell is he talking about?
"I've been there for eight presidents, Democrat and Republican, I've disagreed and I've agreed. But every president I have served with including the Republicans has had a moral center about what it was to be an American, about what we're supposed to do, about what basic fundamental rights are," Biden said.
At the debate, Clinton said Trump had rooted for the housing collapse in 2006 because he saw it as a way to go in and make money. Trump responded, "That's called business, by the way."
Biden said Trump "brags about gaming the system and bankruptcy."
Biden appeared at Drexel University on National Voter Registration Day. The Clinton campaign said he would launch a voter-registration drive and urge Pennsylvanians to register to vote.
"My name is Joe Biden and I work for Hillary Clinton," Biden told the crowd at the start of his remarks Tuesday.
He also mentioned his and his wife's excitement over the undefeated Eagles and rookie QB Carson Wentz. He complemented the tough Philly sports fans.
