The eighth person in the room where Donald Trump Jr.’s collusion with Russia happened has been identified, but—at least right off the bat, before we dig into Ike Kaveladze’s background—this is the most interesting piece of news coming out:

Balber said Tuesday that he received a phone call from a representative of Special Counsel Robert Mueller over the weekend requesting the identity of the Agalarov representative , which he said he provided. The request is the first public indication that Mueller’s team is investigating the meeting.

You had to figure that Mueller would be investigating, but confirmation is newsworthy. And if the Trumps are not crapping themselves over Mueller’s interest, they’re even more arrogant and/or stupid than I thought. They’re not going to be able to derail him by trying to change the subject or whip up their supporters on Twitter.
