Turns out current SCOTUS nominee Brett Kavanaugh was for prosecuting POTUSes before he was, like, totally against it. 

Here, via Jeffrey Toobin, is his POV when he was on the Starr commission investigating Pres. Clinton in the 1990s:

Kavanaugh, who “was considered one of Starr's intellectual heavy-lifters, pushed hardest to confront Clinton with some of the dirtiest facts linked to his sexual indiscretions with Lewinsky.” In a memo to Starr, he proposed that Clinton be asked the following questions, among others, before the grand jury: “If Monica Lewinsky says that you ejaculated into her mouth on two occasions in the Oval Office area, would she be lying? . . . If Monica Lewinsky says that on several occasions you had her give [you] oral sex, made her stop, and then ejaculated into the sink in the bathroom off the Oval Office, would she be lying?” Starr apparently thought better of this plan ...

Then Kavanuagh thought better of the whole “Are presidents above the law?” thing:

Kavanaugh's service in the Bush White House—and, perhaps, his view of future Republican Presidential patrons—led him to revise his Clinton-era view of the rights of Presidents who are under investigation. In a law-review article from 2009, Kavanaugh said that Presidents should not only be free from the possibility of indictment while in office but should also be allowed to avoid questioning from law-enforcement officials. He wrote that Congress should “consider a law exempting a president—while in office—from criminal prosecution and investigation, including from questioning by criminal prosecutors or defense counsel.”

Here are four questions I'd like to ask him:

1. You‘ve been appointed to the highest court in the land by a president who gained office with help from Russia. How do you feel about that?
2. Because of your views on presidents being above the law, would you recuse yourself from any decision involving Pres. Trump’s Russian scandal and/or Robert Mueller's investigation into same?
3. If it turns out Pres. Trump's connections to Russia go deeper than already revealed, to the point where we have to question his loyalty to this country, would you resign?
4. Have you ever ejaculated into your wife's mouth?
