Oh Snap! Watch Joe Biden Burn Donald Trump by Telling Him to "Grow Up"

Looks like the tension between Joe Biden and President-elect Donald Trump isn't going away anytime soon. The current vice president sat down with PBS NewsHour and was asked about Trump's controversial tweets (such as calling Senate Minority Leader Chuck Schumer a "clown") since winning the 2016 presidential election. "Grow up, Donald. Grow up," Biden said. "Time to be an adult. You're president. You've got to do something."

Biden also called on Trump to "show us what you have." "You're going to propose legislation. We're going to get to debate it. Let the public decide," he told PBS's Judy Woodruff. "Let them vote in Congress. Let's see what happens."

This comes after Biden suggested, pre-election, that he would have liked to take Donald Trump "behind the gym" and fight him if they were in high school. Biden also once called Trump "stupid" while campaigning for Hillary Clinton. Ouch! Something tells us Trump will have a few choice words about Biden's recent comments on Twitter pretty soon.
