Vice President Joe Biden sat down with “Tonight Show” host Jimmy Fallon on Thursday to talk about the debate between Donald Trump and Hillary Clinton.

But before the conversation really got started, Biden had to get something off his chest.

“Bless me, Father. I’m about to sin,” Biden said, then unloaded on Trump for claiming he was “smart” for not paying taxes.

“What does that make the rest of us ― suckers?” Biden asked.

“It angers me, quite frankly,” Biden said. “It’s one of the things that the American people really resent: The American people don’t like being played for suckers.”

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S.
