Graham, a House prosecutor in the impeachment trial of former President Clinton, was asked if firing Mueller would be an impeachable offense during an interview on Hugh Hewitt's radio program.

"Probably so, if he did it without cause, yeah," Graham responded. 

"I think what the president will have done is stopped an investigation in whether or not his campaign colluded with the Russians, what effect the Russians had on the 2016 campaign. I can’t see it being anything other than a corrupt purpose," Graham explained. 

Graham said that while he has seen no evidence of collusion between Trump associates and Russians, "to stop investigation without cause, I think, would be a constitutional crisis." 

Graham's comments came after Trump attorney John Dowd called last week for Deputy Attorney General Rod RosensteinRod Jay RosensteinScrutiny ramps up over Commerce secretary's stock moves Grassley wants to subpoena Comey, Lynch after critical IG report Top House Dem claims Judiciary chairman's DOJ, FBI subpoena is invalid MORE to "bring an end" to Mueller's probe.

Trump, Graham said, is not without reason for being upset with the Department of Justice over its surveillance of members of his 2016 campaign. But he said Mueller should be left alone.

"He would be wrong, in my view, to try to stop this investigation without cause on the Mueller side," he said. 

Earlier this week, Graham pledged to make sure Mueller's investigation continues without any political interference, and warned that Trump firing the special counsel would herald "the beginning of the end of his presidency." 

Trump reportedly ordered for the firing of Mueller earlier on in Mueller's investigation, but withdrew after top White House lawyers threatened to resign over the matter.

King said that it would be a “crisis” if Trump fired Mueller, but noted that he does not see it as an impeachable offense.

“High crimes and misdemeanors is the standard for impeachment, and I have a high standard for impeachment,” King told Hewitt. “I don’t think impeachment should be used to change a government you don’t like.”

“I wouldn’t say it rises to the level of an impeachable offense, but I certainly think it’s going to create a real problem,” he added.
