United States Vice-President, Joe Biden, has advised President-elect, Donald Trump to “grow up” and criticised his attacks on the intelligence community.

The advice came over Donald Trump’s disagreement about the Russia hacking allegations of the US elections.

Joe Biden said it was “absolutely mindless” for the president-elect not to have faith in intelligence agencies.

Ceoafrica gathered that Russia denied the hacking alleged to have aided Hillary Clinton’s defeat by Donald Trump.

Late on Thursday, Trump questioned how intelligence agencies were confident about the alleged Russian hacking “if they never even requested an examination of the computer servers belonging to the Democratic National Committee (DNC)”.

“For a president not to have confidence in, not to be prepared to listen to, the myriad intelligence agencies, from defence intelligence to the (Central Intelligence Agency (CIA), is absolutely mindless,” Joe said during an interview.

“The idea that you may know more than the intelligence community knows is like saying I know more about physics than my professor. I didn’t read the book, I just know I know more.”

When asked what he thought of Trump’s regular attacks on Twitter, Joe Biden said: “Grow up Donald, grow up, time to be an adult, you’re president. Time to do something. Show us what you have.”

He thereafter called Donald Trump “a good man.”               

It would be recalled that the Russia’s hacking about the US election led to Russian Diplomats sack in the US, after Obama promised to get back at Russia in his 2016 end of the year message.
