NSA Director Mike Rogers told his staff there is 'damning' evidence Donald Trump and his team colluded with the Russian government, a former agent claims.

The shocking information was allegedly relayed to all staff in an agency-wide meeting this week, ex-NSA agent John Schindler claimed Friday.

Schindler wrote in the New York Observer the security chief started the meeting by telling staff they were not going to like what he disclosed to them, but he had to: 'tell what (he) had seen'.

'Rogers then added that such SIGINT exists, and it is damning,' the ex-agent wrote.

'He stated, "There is no question that we [meaning NSA] have evidence of election involvement and questionable contacts with the Russians."

'Although Rogers did not cite the specific intelligence he was referring to, agency officials with direct knowledge have informed me that DIRNSA was obviously referring to a series of SIGINT reports from 2016 based on intercepts of communications between known Russian intelligence officials and key members of Trump’s campaign, in which they discussed methods of damaging Hillary Clinton.'

The security expert went on to support reports alleging the president asked Rogers - along with National Intelligence Director Dan Coats - to 'go public in denying that Team Trump had any ties to Russia during the 2016 election campaign'.

'Asking top intelligence officials to publicly attack the FBI and its director isn’t just unusual - it’s unprecedented, he wrote in the Observer.

The new report claims Trump also asked the NSA boss to publicly deny Trump and his team has ties to Russia

'Even President Nixon, in the depths of the Watergate scandal, which ultimately unraveled his administration, never went quite so far as to drag NSA into his public mess.

'Admiral Rogers anecdotally flatly denied Trump’s request, which - if true - was inappropriate, unethical and dubiously legal.'

Schindler then closed his statements by calling on the politicians to allow Rogers to share what he knows.

'It’s therefore high time for the House and Senate intelligence committees to invite Admiral Rogers to talk to them about what transpired with the White House,' he said.

'Since Mike Rogers is said to have kept notes of the president’s effort to enlist him in Trump’s personal war with the FBI, as any seasoned Beltway bureaucrat would do, his account ought to be impressively detailed.'
