Former FBI Director James Comey is warning that calls to probe the FBI and special counsel's Russia probe would lead to 'terrible cycle' of investigation.

Comey's own interactions with Trump before the president fired him were a subject of Special Counsel Robert Mueller's investigation. Now, withe the completion of the Mueller report, Trump and Republican allies called for an investigation of the Mueller probe, the Clinton email investigation, and any FBI misconduct that occurred.

Trump himself on Tuesday renewed his call to look at the origins of the Russia probe – the 'beginnings and where it started, the whole situation.'

The president said some 'very bad people started something that should have never been started' and that they 'did things that were very, very bad for our country and very, very illegal – and you could even say treasonous.'

'What would be the crime you'd be investigating?' former FBI Director James Comey said when asked about calls for an investigation of the Russia and Clinton email probes

Comey was asked in an interview with CNN whether he was fearful of what may come amid calls by Trump and powerful officials such as Trump ally Judiciary Chairman Sen. Lindsey Graham.



'I don't fear it personally. I fear it as a citizen, right? Investigate what? Investigate that investigations were conducted? What would be the crime you'd be investigating?' Comey asked.

Then Comey was asked whether he and the FBI could have done more to 'lock her up' chants that were a staple of Trump's 2016 campaign. Audience members continue to erupt into the cheer at Trump's rallies.

'So it's a terrible cycle to start. He's already started it with calling for the locking up of his political opponents, including people like me and so it would just be more of that dangerous step and would I hope, though they'll continue to disappoint me, the Republicans would finally stand up and say we don't that kind of thing,' Comey added.

Then interviewer Christianne Amanpour brought up the 'lock her up' chants that erupted at Trump rallies during the 2016 campaign, and whether he or the FBI somehow could have done more to shut it down.

'That's not a role for government to play,' responded Comey. 'The beauty of this country is people can say what they want even if it's misleading and it's demagoguery.'

'The people should have shut it down were Republicans who understand the rule of law and the values that they claim to stand for. Shame on them, but it wasn't a role for government to play,' he said.
