United States President-elect, Mr Donald Trump, says he does not believe a CIA assessment that Russian hackers tried to sway the election in his favour.

In an interview on Sunday, he blamed democrats for ridiculous reports that accused Russia of perpetrating the attacks.

Meanwhile, Russian officials have repeatedly denied the hacking allegations as senior republicans joined democrats in calling for a full investigation into the intelligence.

Republican senator and Chairman of the Senate Armed Services Committee, John McCain, said in a joint statement with top democratic senator, Chuck Schumer and others that the CIA’s report should alarm every American.

The hacks, targeting emails at the Democratic Party and the emails of a key aide to presidential nominee Hillary Clinton, were said to have shaken the presidential campaign.
