Story highlights Trump took to Twitter Tuesday evening to once again deride US intelligence agencies

It's his latest attempt to undermine their conclusion that Russia hacked Democratic groups

Washington (CNN) President-elect Donald Trump took to Twitter Tuesday evening to deride the US intelligence agencies due to brief him on alleged Russian hacking of American political groups.

The "Intelligence" briefing on so-called "Russian hacking" was delayed until Friday, perhaps more time needed to build a case. Very strange! — Donald J. Trump (@realDonaldTrump) January 4, 2017

It was his latest attack on a key body he will rely on as commander in chief and again put him at odds with the agencies' unanimous conclusion that Russia hacked Democratic Party groups and individuals to interfere in the US presidential election.

Trump suggested that intelligence officials postponed an " 'intelligence' briefing on so-called 'Russian hacking' " that they were set to deliver to him this week because they might need more time "to build a case." He called the alleged delay "very strange."

Trump tweeted Wednesday , "Julian Assange said 'a 14 year old could have hacked Podesta' - why was DNC so careless? Also said Russians did not give him the info!"

Trump said last week that he would receive an intelligence briefing on the Russian breaches this week and suggested it would come early on, telling reporters on New Year's Eve that they would know more about the subject "Tuesday or Wednesday."
