President Donald Trump today called the ongoing controversy about his White House campaign linked to Russia a “total scam.”

US authorities are conducting investigations about the direct connection between campaign officials and Russia operatives, amid Trump’s insistence about no such contact.

“It is the same Fake News Media that said there is ‘no path to victory for Trump’ that is now pushing the phony Russia story,” Trump tweeted. “A total scam!”

There has been no clear evidence that Russian operatives and Trump campaign officials colluded to defeat Clinton.

The most recent turn of events is that Michael Flynn, fired as Trump’s national security adviser for not disclosing talks with at least one Russian official, is purportedly seeking immunity in exchange for testifying in the Capitol Hill probes.

Following those revelations, Nunes, who was a member of the presidential transition team, has resisted calls to step aside from his committee’s investigation.
