Trump attacks intelligence agencies over report on Russia ties
President-elect Donald Trump has condemned US intelligence agencies, blaming them for leaking unsubstantiated reports on his relationship with Russia.
A US official said that intelligence officials had informed Mr Trump about an unsubstantiated report that Russia had compromising personal and financial information about him.
President-elect Trump and President Barack Obama were briefed on the intelligence community's findings last week, the official said.
Mr Trump angrily denounced the reports, citing Russia's denials and suggesting anew that he is being persecuted for defeating other GOP presidential hopefuls and Democrat Hillary Clinton in the election.
"I win an election easily, a great 'movement' is verified, and crooked opponents try to belittle our victory with fake news. A sorry state," he tweeted.
"Intelligence agencies should never have allowed this fake news to 'leak' into the public. One last shot at me. Are we living in Nazi Germany?"
The topic appears certain to come up at a previously scheduled new conference later on Wednesday.
The conference had been designed for Mr Trump to discuss whether and how he plans to avoid conflicts of interest with his global business empire.
The last time President-elect Trump held a news conference, he was fighting a heated general election campaign with Ms Clinton and suggested Russia could help dig up some of his rival's emails.
Mr Trump is certain to face questions about what role he believes Russia played in the election year hacking of Democratic groups - interference the intelligence community says was intended to help the Republican defeat Clinton.
