A sixth person who attended the June 2016 meeting at Trump Tower with Donald Trump Jr. and a Russian lawyer has been identified as a translator.

Ken Vogel, a reporter for the New York Times, told MSNBC on Friday the sixth person is Anatoli Samochornov, a translator who worked with Russian lawyer Natalia Veselnitskaya for several years.

Samochornov worked with Veselnitskaya during her efforts to overturn the Magnitsky Act, a 2012 law that sanctioned Russian human rights violators and angered Russian President Vladimir Putin.

Vogel said the translator also worked for the State Department as a contractor assisting with translation and interpretation services.

The meeting at Trump Tower last year has caused concern among Republicans and Democrats on Capitol Hill and cast a shadow on the White House this week. Trump Jr. said he accepted the meeting with Veselnitskaya, orchestrated through British publicist Rob Goldstone, because he was promised damaging information on Hillary Clinton.

In emails revealed by Trump Jr. earlier this week, Goldstone said the information was part of the Russian government's efforts to assist Trump's campaign.

It was initially believed that Trump Jr., Veselnitskaya, then-Trump campaign chairman Paul Manafort, and Jared Kushner, the president's son-in-law, were the only ones who attended the meeting.

But the Associated Press and NBC News reported Friday a fifth person, identified as a Russian-American lobbyist named Rinat Akhmetshin, was also there.

Neither Trump Jr. nor the White House disclosed that others beside Trump Jr., Manafort, Kushner, and Veselnitskaya attended the meeting.
