President Trump has faced enormous criticism following the sacking of James Comey, with former director of national intelligence James Clapper calling it an assault on democracy.
Clapper said Sunday, "At the time we did our intelligence community assessment [of Russian interference in the election], which we published publicly on the 6th of January, there was no evidence of any collusion included in that report".
When asked about what concerns he has for the country ahead, Clapper said that as a private citizen, he worries about America's institutions, which he feels are "under attack" from both external and internal sources.
Clapper said America's founding fathers had created three co-equal branches of government with checks and balances, but with Trump as president, that was now "eroding". "I think as well our institutions are under assault internally".
Director of National Intelligence James Clapper testifies during a hearing before the House (Select) Intelligence Committee on November 17, 2016 on Capitol Hill in Washington, D.C.
The former USA national intelligence director says the global "ransomware" attack could grow much larger when people return to work.
Comey's congresional testimony, along with that of ex-acting Attorney General Sally Yates, reportedly ticked off President Trump.
But that's not exactly what Clapper said, the former DNI chief again explained Sunday.
The Justice Department has said Sessions and his deputy, Rod Rosenstein, were involved in the interviews because the Federal Bureau of Investigation director reports to them as attorney general and deputy attorney general.
'Director Clapper reiterated what everybody, including the fake media already konws- there is "no evidence" of collusion w/ Russian Federation and Trump, ' the president tweeted.
The Senate must confirm a new FBI director once Trump names a candidate; that FBI director will take a lead role in the Russian Federation investigation.
Sen. Lindsey Graham, R-S.C., asked Clapper how it could be that the FBI was investigating whether there was collusion, but, at the same time, signed off on an assessment that said there was no evidence of it.
In short, the FBI's investigation could still produce evidence of collusion.
But he said it's a "professional courtesy" to accept an invitation from the president for dinner.
"The developments of the past week are very bothersome, very disturbing to me", Clapper said on CNN's "State of the Union" on Sunday. "I don't know of any evidence to it".
