Graham rips Comey for misleading Congress

A source told CNN on Wednesday Comey has spoken privately with special counsel Robert Mueller to work out the parameters for his testimony to ensure there are no legal entanglements as a result of his public account.

Since his firing last month, dramatic accounts have emerged in The New York Times, CNN and elsewhere about the tense confrontations with Trump that Comey memorialized in memos afterward.

A week after he took office in January, Trump allegedly demanded Comey’s “loyalty” if he kept him on as FBI director, and he urged Comey to drop his ongoing investigation into Michael Flynn, Trump’s fired national security adviser, in a separate, one-on-one meeting.

This story is breaking and will be updated.
