His name is Rob Goldstone. He’s a British publicist, and a friend of the Trumps.

He’s also the man that acted as the go-between to set up the June 2016 meeting at Trump Tower between Donald Trump Jr. and a group of Russians.

Apparently, Mr. Goldstone has been living in Thailand and now he’s ready to talk to Robert Mueller.

Goldstone’s lawyer, G. Robert Gage won’t comment further on developments, other than to say that nothing has been set up, as yet.

Other sources that are close to Goldstone say he’s been in talks with Mueller and a trip to the states should be expected sooner, rather than later.

Goldstone was actually in the room during the meeting between Trump Jr. and the Russians, as was former Trump campaign chairman Paul Manafort, and White House senior adviser (and Trump son-in-law) Jared Kushner.

I’m sure his involvement from the beginning makes Goldstone a coveted witness. According to NBC News:

In an email that later became public, Goldstone wrote to Trump Jr. that “the Crown prosecutor of Russia … offered to provide the Trump campaign with some official documents and information that would incriminate Hillary and her dealings with Russia and would be very useful to your father.”

There is no office of crown prosecutor, but Goldstone appeared to be referring to the Russian prosecutor general.

He added that “this is obviously very high level and sensitive information but is part of Russia and its government’s support for Mr. Trump — helped along by Aras and Emin,” a reference to his long-time clients, oligarch Aras Agalarov and his son, Emin, a Russian pop singer. Much of Goldstone’s publicity business involves music promotion. He also represented the Miss Universe pageant, at one time owned by President Trump.

Trump Jr’s reply to his offer of Russian help was, “I love it.”

Besides Trump Jr., Goldstone, Manafort, Kushner, and of course, the Russian lawyer, Natalia Veselnitskaya, there was Irakly “Ike” Kaveladze, an employee of the Agalarov family, working in the U.S., and Rinat Akhmetshin, a Russian-American lobbyist, working to get the Obama-era sanctions lifted from Russians and their interests.

Also in the room was Russian-American translator Anatoli Samochornov, who had done work for the State Department and had translated previously for Veselnitskaya.

Investigators are trying to determine whether the promised assistance from the Russian government was provided, and whether it was part of what a dossier compiled by a former British intelligence officer called “a well-developed conspiracy of cooperation” between the Trump campaign and Russia.

The interesting twist is that Veselnitskaya told NBC News that she got the incriminating information, mostly centered around tax evasion and Democrat donations, from Glenn Simpson, owner of Fusion GPS.

Simpson was hired to do research for a New York federal court case, at that time.

A source with firsthand knowledge of the matter confirmed that the firm’s research had been provided to Veselnitskaya as part of the case, which involved alleging money-laundering by a Russian company called Prevezon.

Veselnitskaya said she turned Simpson’s research over to the Russian prosecutor.

What Goldstone will add, or why he wants to talk to Mueller is up for debate.
