Biden to Trump: 'Grow Up, Donald. Time to Be an Adult'

Vice President Joe Biden told President-elect Donald Trump on Thursday that it's time to grow up when it comes to the frequent barbs lobbed via his Twitter account. “Grow up, Donald,” Biden said, interrupting Judy Woodruff on "PBS Newshour" as the anchor recited some of Trump’s recent tweets about President Barack Obama and Senate Minority Leader Chuck Schumer.
