"Please, America, don't go down the road entitled 'impeachment,'" Starr, who investigated President Bill Clinton during the Monica Lewinsky scandal 20 years ago, said in a recent interview with Vice.
And although his investigation ended with the impeachment of Clinton, Starr now thinks that course of action is "the wrong way to go." Not because he supports Trump. Rather, the fallout of the Lewinsky scandal has taught Starr that the American people aren't keen on impeachment.
"We've had two presidential impeachments [in US history]. Neither has succeeded," Starr explained. "[N]ow we know from the Clinton investigation that the president can even be proven of crimes, but - unless there's a close nexus with the conduct of the office itself - even a federal criminal can continue to occupy the office of the presidency, in the view of the American people."
That nexus would include crimes like taking a bribe or committing a flagrant act of treason. Short of those sort of horrendous offenses, Starr doesn't think the general public would support impeachment over letting the American electoral system run its course.
"I think the American people have this wise instinct for stability, and [allowing] the electoral process to go forward," Starr explained.
But that doesn't mean Trump would get away with misconduct or anything else that Mueller might dig up during the investigation. Starr thinks that the president could face criminal charges after he leaves office. So if the Democratic challenger proves successful in 2020, Trump could leave the White House in the back of a cop cruiser instead of aboard Marine One.
