"You look at the accounts we have just in the press the last few days its stunning, stunning, the conclusions reached by the press. Thank goodness we've got them still around ... this is not fake news, okay?" he added.
 
The Washington Post on Friday reported that the CIA concluded Russia was intervening in the election specifically to help Trump.
 
Reid said he believed Comey was aware of the concerns of Russian interference in the election but chose not to release the information before Election Day.
 
"I am so disappointed in Comey. He has let the country down for partisan purposes," he added, calling for the FBI head's resignation.
