Washington, April 16: Former FBI Director James Comey, in his first interview since being fired last May, said that Donald Trump is “morally unfit” to be US President, a “serial liar” who treated women like “meat” and it was “possible” that Russians had material that could be used to blackmail him. In an exclusive interview with ABC News’ chief anchor George Stephanopoulos on Sunday night, he also described him as a “stain” on everyone who worked for him. The former head of the Federal Bureau of Investigation compared the Trump administration to a “mafia family” and said that the President was incinerating the country’s crucial norms and traditions like a “wildfire”.
