Trump on verge of firing national security adviser after he admitted Russia's role in US election: report

President Donald Trump could fire his national security adviser, Lt. Gen. H.R. McMaster, after he said that evidence of Russia's interference in the 2016 U.S. election was "incontrovertible."

Sources close to the White House told CNN that Pentagon officials were "quietly" trying to find a job for McMaster in the Pentagon.

"Several sources told CNN that the push for a replacement comes after months of personal tension between McMaster and Trump," the report said.

According to CNN, the desire to fire McMaster as national security adviser was reinforced after his recent remarks about Russia's role in helping Trump to get elected.

"As you can see with the FBI indictment, the evidence is now really incontrovertible and available in the public domain, whereas in the past it was difficult to attribute," McMaster said at a security conference this month.

Trump responded with a tweet.

"General McMaster forgot to say that the results of the 2016 election were not impacted or changed by the Russians and that the only Collusion was between Russia and Crooked H, the DNC and the Dems," Trump complained. "Remember the Dirty Dossier, Uranium, Speeches, Emails and the Podesta Company!"

Sources told CNN that Trump prefers to be briefed by CIA Director Mike Pompeo or Defense Secretary James Mattis, "who patiently answer his questions, regardless of the premise."

"McMaster, meanwhile, is the person who delivers the news that Trump doesn't want to hear on a daily basis," CNN reported.
