News broke Friday that Rinat Akhmetshin, who received USA citizenship and became a Washington lobbyist after emigrating from Russian Federation more than a decade ago, was also present at the Trump Tower meeting with campaign officials and Kremlin-linked lawyer Natalia Veselnitskaya.
The lobbyist, first identified by the Associated Press as Rinat Akhmetshin, denies any current ties to Russian spy agencies.
Trump Jr. said after releasing the emails that, "in retrospect, I probably would have done things a little differently".
According to Akhmetshin, the Post reported, Veselnitskaya had said she had financial information on a U.S. hedge fund with links to Clinton's Democratic Party, and left a document behind at the meeting.
The associate stated that the discussion was part of a Russian Government effort to help the GOP candidate.
Trump Jr. earlier this week said publicly he had met Veselnitskaya in June 2016, despite earlier claims that he - and other members of the Trump campaign team - had not met with any Russians during Trump's election campaign.
Even if she ended up having no actual dirt on Clinton, Trump Jr. still took the meeting, Elleithee said. Veselnitskaya presented the contents of the documents to the Trump associates and suggested that making the information public could help the Trump campaign, he said. Trump Jr. then lost apparent interest, according to Akhmetshin.
Rep. Adam Schiff of California says Trump Jr.'s shifting explanations "paint a portrait of consistent dissembling and deceit".
Jared Kushner, Senior Advisor to President Donald J. Trump, sits in on a meeting with Marine Corps Gen. Joseph F. Dunford Jr., chairman of the Joint Chiefs of Staff, at the Ministry of Defense in Baghdad, Iraq, April 3, 2017. Meanwhile, Kushner's spokesperson and Trump Jr.'s attorney, Alan Futerfas, did not respond to the AP's request for comment. Veselnitskaya reportedly believed the documents detailed the flow of illicit funding to the Democratic National Committee.
Why was Akhmetshin at the meeting?
Mr. Trump's former campaign manager denies any collusion.
Asked about Mr Akhmetshin, Russian President Vladimir Putin's spokesman, Dmitry Peskov, told reporters: "We don't know anything about this person".
During his years working in the shadowy Washington DC world of corporate intelligence, his connections to former Russian agents were pitched as a valuable asset to private clients.
Grassley's committee is one of several congressional panels investigating the Trump campaign's links with Russian Federation, while Special Counsel Robert Mueller, a former Federal Bureau of Investigation director, is heading a criminal probe into the election interference and whether the president obstructed justice by firing another Federal Bureau of Investigation director, James Comey, while he was heading the Russian Federation probe before Mueller took over.
"I think any witness who's been asked to testify before Congress should testify", Ryan said. He says he will appear voluntarily before the panel.
