Mr Trump also renewed his criticism of Hillary Clinton, claiming she should "never have been allowed to run"
President-elect Donald Trump has hit out at Hillary Clinton and what he has described as "sleazebag" political operatives in a new series of tweets.
He has also pledged that his administration will 'within 90 days' have a full report on alleged Russian hacking during the US election campaign.
Mr Trump continued his criticism of the controversial dossier that makes allegations about links between the President-elect and Russia. The document was published in full by BuzzFeed, who emphasised that the claims were unverified.
The President-elect has again alleged that the document - which was put together by a former British spy for opposition research during the election campaign - was likely leaked by "intelligence".
An ex-M16 officer was commissioned to compile the report by a Washington firm on behalf of Mr Trump's political opponents. It is said to have circulated among the media and politicians before making its way to the intelligence community.
Mr Trump said it was released "knowing there is no proof, and never will be".
It now turns out that the phony allegations against me were put together by my political opponents and a failed spy afraid of being sued....— Donald J. Trump (@realDonaldTrump) January 13, 2017
Totally made up facts by sleazebag political operatives, both Democrats and Republicans - FAKE NEWS! Russia says nothing exists. Probably...— Donald J. Trump (@realDonaldTrump) January 13, 2017
released by "Intelligence" even knowing there is no proof, and never will be. My people will have a full report on hacking within 90 days!— Donald J. Trump (@realDonaldTrump) January 13, 2017
James Clapper, Director of National Intelligence in the US, said in a statement on Wednesday that he told Mr Trump he did not believe the dossier was leaked by the intelligence community.
Mr Clapper explained: "I emphasised that this document is not a US Intelligence Community product and that I do not believe the leaks came from within the IC.
"The IC has not made any judgment that the information in this document is reliable, and we did not rely upon it in any way for our conclusions," he added.
Mr Trump also today renewed his criticism of his former presidential rival Hillary Clinton, seemingly responding to the news that a US watchdog is investigating "certain actions" by FBI and US justice department officials during the election campaign.
The justice department’s inspector general will be investigating FBI Director James Comey regarding the Clinton email investigation, and whether investigative decisions may have been based on "improper considerations".
Less than a fortnight before the election, Mr Comey announced that the FBI had discovered new emails that may have resulted in the agency reopening an investigation into Mrs Clinton's use of a private email server while she was secretary of state.
Only days before the election he announced they had discovered no new evidence - but Mrs Clinton later blamed the initial announcement for her defeat.
Today, Mr Trump claimed Mrs Clinton "should never have been allowed to run".
What are Hillary Clinton's people complaining about with respect to the F.B.I. Based on the information they had she should never.....— Donald J. Trump (@realDonaldTrump) January 13, 2017
