Biden's message to Trump: Grow up, stop tweeting

Vice President Biden said Thursday that his advice for President Trump would be to grow up and stop using his Twitter account.

The Hill reported that Biden made the comment during a talk at the University of Pennsylvania’s Biden Center for Diplomacy and Global Engagement.

“I would stop tweeting and start focusing,” Biden said.

This is not the first time Biden has been critical of Trump. Back in October, Biden said that he wished he could physically confront then-nominee Trump over lewd comments the real estate mogul made about women that were captured on tape in 2005.

"The press always asks me don’t I wish I were debating him," Biden, 73, said of the 70-year-old Trump. "No, I wish we were in high school—I could take him behind the gym. That’s what I wish."

Biden said on Thursday that “words of a president matter.”

“They have enormous, enormous, enormous, reverberating sounds around the world," Biden said. "Every time a U.S. president speaks and says something, leaders and people around the world try to dissect what he means because it matters so much to their security, threats they face, whatever it is. So, you can't loosely make assertions without limiting your ability to lead."
