WASHINGTON, D.C. (CNN)--Another player has emerged in that June 2016 Trump Tower meeting between Donald Trump Jr. and Russian lawyer Natalia Veselnitskaya.
Despite Don Jr.'s insistence he disclosed everything there was to know about the meeting with the release of several emails Tuesday, today there is news that Russian-American lobbyist Rinat Akhmetshin was also in attendance.
Akhmetshin told the Associated Press he was in the room for the 20-30 minute meeting with Trump's eldest son and Veselnitskaya--that also included publicist Rob Goldstone, campaign chair Paul Manafort and Donald Trump's son-in-law Jared Kushner, who is now a top advisor to the President. CNN has learned at least two others were in the room: a translator and a representative of the Agaralov family.
Akhmetshin is a registered lobbyist for Veselnitskaya's organization that has focused on overturning the American sanctions against human rights abusers in Russia, according to lobbying records.
Akhmetshin's lobbying caught the attention of Sen. Chuck Grassley (R-Iowa) who described him as a Russian immigrant "acting as an unregistered agent for Russian interest" with "ties to Russian intelligence."
That was in a letter to Homeland Security Secretary John Kelly, requesting Akhmetshin's immigration history earlier this year.
Akhmetshin denied to the Washington Post that he served as a Russian intelligence agent.
"I never worked for the Russian government. I served as a soldier for two years. At no time have I ever worked for Russian government or any of its agencies. I was not an intelligence officer. Never," Akhmetshin said.
The email chain released Tuesday indicated there was another person at the meeting. The British publicist who arranged it, Rob Goldstone, wrote this to Donald Trump Jr. two days before.
"I will send the names of the two people meeting with you for security when I have them later today," Goldstone wrote.
No email producing those names was ever released by Donald Trump Jr. President Trump defended his son while speaking in Paris.
"As far as my son is concerned, my son is a wonderful young man. He took a meeting with a Russian lawyer. Not a government lawyer, but a Russian lawyer. It was a short meeting," Trump said.
President Trump continues to insist he didn't know anything about the meeting until several days before Donald Trump Jr.'s emails were released.
On Friday morning, counselor to the President Kellyanne Conway seemed to suggest that more evidence was needed to prove collusion.
"The goalposts have been moved. We were promised hard evidence of systemic, sustained furtive collusion," Conway said.
The scramble to respond to the details trickling out may have exposed some White House aides to special counsel scrutiny. They could be called by Robert Mueller and his team to explain what they learned about this June 2016 Trump Tower meeting.
Sources close to Jared Kushner's legal team say White House aides and Kushner's lawyers began straregizing in late June how to manage any later disclosure of the emails Kushner's team discovered from Donald Trump Jr.
