It’s kind of funny. But this is a real legal issue:

Is President Donald Trump mentally competent to stand trial? While the question itself may seem like something of a troll, there’s at least one high-profile legal professional who apparently doesn’t think so.

Former White House ethics lawyer current Minnesota Law School Professor Richard Painter publicly considered the notion.

“This statute, if embodied in the rules of the Senate, will probably indefinitely postpone an impeachment trial,” Painter tweeted on Friday evening. “The Chief Justice could so rule. 18 U.S. Code § 4241 – Determination of mental competency to stand trial.”
