This isn’t happening. This cannot be allowed to happen. If Donald J. Trump allows it, he’s got a noggin full of rocks.

Vladimir Putin reportedly floated the idea with the president over whether Russian government officials could question a former U.S. ambassador to Russia, Michael McFaul.

Trump then reportedly took the suggestion seriously and has asked White House legal eagles to examine whether it’s possible.

I repeat: This cannot be allowed to happen.

Putin apparently wants to interrogate McFaul in the wake of the Justice Department indictment of 12 Russian military intelligence officers. He might want to pick McFaul’s brain to figure out what he knew, if anything, about anything involving the Trump presidential campaign.

This is ridiculous, absurd, utterly frightening proposal coming from the former head of the Soviet Union’s spy agency, the KGB. To suggest that we could compel a former ambassador to talk to a foreign hostile power is preposterous on its face.

McFaul wrote this, according to Politico: “I hope the White House corrects the record and denounces in categorical terms this ridiculous request from Putin,” McFaul tweeted Wednesday. “Not doing so creates moral equivalency between a legitimacy US indictment of Russian intelligence officers and a crazy, completely fabricated story invented by Putin.”

Putin is an even more egregious liar than his pal in the White House. And, man, that’s saying something.
