Joe Biden To President-Elect Trump: "Grow Up, Donald"
The 74-year-old vice president told the 70-year-old president-elect that "it's time to be an adult."
Joe Biden has urged Donald Trump to "grow up" amid an ongoing row over the president-elect publicly doubting US intelligence agencies.
The 74-year-old vice president was responding, in an interview with PBS NewsHour, to a question about Trump's notorious use of Twitter.
Trump, 70, recently tweeted about FBI findings that Russia was behind the hack of the Democratic National Committee amid suggestions it had tipped the scales of the presidential election in his favor.
“Time to be an adult," Biden said. "You’re president. You’ve got to do something. Show us what you have."
The vice-president also commented on Trump's criticisms of the intelligence agencies, calling them "worrisome" and "absolutely mindless."
"For a president not to have confidence in, not to be prepared to listen to, the myriad intelligence agencies, from defense intelligence to the CIA, is absolutely mindless," he said.
Biden added that the intelligence community found "overwhelming evidence" that "Russia did engage in an effort to impact" the US election.
