This is Trump praising Putin's "incredible offer" to have Russian agents work with Mueller to investigate Russian agents accused of hacking to influence and disrupt American elections.
Part of the incredible offer was Putin's request to question a former US ambassador to Russia, Michael McFaul. Asked about the possibility,
Sarah Huckabee Sanders suggested the idea was under consideration. “The president is going to meet with his team, and we’ll let you know when we have an announcement on that,” she said at Wednesday’s press briefing. “He said it was an interesting idea. He didn’t commit to anything. He wants to work with his team and determine if there’s any validity that would be helpful to the process…. It was an idea they threw out,” she added.
This is, of course, absurd. We don't hand over ambassadors for interrogation by the Russians. Imagine the howling outrage if the Obama WH ever even gave a hint that he would let the Russians interrogate a current or former ambassador to Russia. Putin himself knows the request is absurd whataboutism, but absurdity in plain sight is standard operating procedure for dictators and authoritarian leaders.
