Vice President Joe Biden threw some shade at Republican presidential nominee Donald Trump during a campaign speech in Charlotte, North Carolina, on Tuesday.

Biden told attendees at a rally that the whole world is watching the presidential race, and “what happens here matters to them.” He chastised Trump for his relationship with Russian President Vladimir Putin and mocked him for his late-night Twitter tendency.

“Can you imagine any president in the history of the United States of America, all the way from George Washington to Barack Obama, assuming the technology existed,” Biden said, “can you imagine any president getting up at 3:30 in the morning and tweets vitriol, attacking a woman for her weight? Talks about women being pigs?”

Biden was referencing tweets Trump sent out in the middle of the night in September mocking former Miss Universe Alicia Machado. Since coming forward about the derogatory comments Trump made about her while she was Miss Universe, Machado has been campaigning for Democratic nominee Hillary Clinton. She spoke at a rally in Florida on Tuesday afternoon.

Biden added that Trump’s candidacy has been bad for America’s image.

“This guy is so dumbing-down, I mean it, America’s brand around the world. It’s outrageous,” he said.

“There’s a lot on the ballot, but one of the things is dignity and respect.”

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.
