Vice President Joe Biden has offered some stern advice to President-elect Donald Trump: lay off the Twitter and act like an adult (video below).
On Jan. 5, Trump took to his Twitter account to blast the Senate Minority Leader, Democratic Sen. Chuck Schumer of New York, and other Democratic lawmakers.
"The Democrats, lead by head clown Chuck Schumer, know how bad ObamaCare is and what a mess they are in," Trump tweeted out.
That evening, Vice President Joe Biden was asked by "PBS Newshour" to respond to that statement as well another tweet where Trump accused President Barack Obama of derailing his transition period.
"Grow up, Donald," Biden responded with a grin. "Grow up. Time to be an adult. You're president. You've got to do something. Show us what you have."
The outgoing vice president also asserted that any statements made by Trump were immaterial and that the American public would judge his leadership once he began governing.
"It's going to be much clearer what he's for and against and what we're for and against now that it's going to get down to actually discussing in detail these issues that affect peoples' lives," Biden concluded.
On Jan. 6, Republican Rep. Chris Collins of New York blasted Biden for his comments, accusing the vice president of behaving spitefully.
"That's a pathetic response," Collins told CNN. "I think it's beneath the office of the vice president. It shows just the angst of the loss of this election by Obama, Hillary Clinton and Joe Biden. Donald Trump is the adult in the room."
Since the 2016 election, Biden has floated the possibility of his own presidential bid in 2020. On Dec. 6, 2016, he jokingly suggested to late night host Stephen Colbert that he would best Trump in stamina.
"You don't know what's going to happen," Biden said, according to ABC News. "I mean hell Donald Trump's going to be 74. I'll be 77 in better shape. I mean, what the hell? Who knows?"
Biden later clarified that he was not committing to a presidential campaign, but will preserve the possibility.
On Jan. 4, a Biden aide confirmed that the vice president will develop partnerships with the University of Delaware and the University of Pennsylvania once he leaves office. In addition, he will continue his efforts to help foster a cure for cancer, AP reports.
