The Washington Post has identified the eighth person in the room for the Trump Tower meeting between Donald Trump Jr. and a Russian lawyer: Ike Kaveladze, a U.S. citizen who works as a vice president for the Crocus Group, the real estate firm owned by Russian Trump associate Aras Agalarov.

Why he was there: Kaveladze's lawyer told the Post he believed he would be acting as a translator during the meeting, but found that Natalia Veselnitskaya, the Russian lawyer, had brought her own. Kaveladze was also there as a representative for the Agalarov family.

One big revelation: Robert Mueller, the special counsel for the government's Russia probe, requested Kaveladze's identity from his attorney over the weekend — the first confirmation that Mueller is looking at the Trump Tower meeting.
