Donald Trump Jr. may get a chance to take the oath and testify in public about his meeting with a Kremlin-linked lawyer and an anti-sanctions lobbyist, now that special counsel Robert Mueller has raised no objection to a Senate appearance.

Mueller, who is heading a Justice Department probe of the Trump campaign's Russia contacts, has given the okay for the president's eldest son to testify in public, Sen. Dianne Feinstein told reporters Tuesday.

Word of his approval came on a day when the identify of an eighth participant in a Trump Tower meeting that included Trump Jr. was revealed to be Ike Kaveladze, a vice president in a real estate firm owned by Russian billionaire Aras Agalarov.

Kaveladze's work features prominently in a 2000 government report on money laundering.

Former FBI Director Robert Mueller, special counsel on the Russian investigation, leaves following a meeting with members of the US Senate Judiciary Committee at the US Capitol in Washington, DC on June 21, 2017. He has given the okay for Donald Trump Jr. to testify before the panel

The General Accounting Office report states that his firm set up more than 2,000 Delaware corporations for Russians without even knowing who owned the companies. Kaveladze called the report, which was detailed in the New York Times at the time, as a 'witch hunt' in an article identifying him as the person behind the transactions.

Paul Manafort, the former Trump campaign chair who also participated in the meeting, would be free to testify.

Trump Jr.'s lawyer has said he welcomes the chance to tell the complete story.

'Don Jr. and his counsel were fully prepared and absolutely prepared to publish or make a statement that was a fulsome statement about the nature of the meeting, what led to the meeting, what the conversation was in the meeting,' his lawyer Alan Futerfas said.

Trump Jr.'s initial statement said the meeting was about adoption issues. He later acknowledged it was about getting potential dirt on Hillary Clinton, and only later was it revealed that the meeting included a Kremlin-linked lawyer, a lobbyist who served in the Soviet military, and a real estate executive accused of laundering Russian money through U.S. banks.

Feinstein's statement made no mention of Trump son-in-law Jared Kushner, who has been revealed to have left more than 100 foreign contacts off his disclosure form when he joined the White House. Numerous Democrats have called for Kushner's security clearance to be revoked. Among those left off were Russians participating in the meeting in Trump Tower in June 2016.

Republican Sen. Richard Burr of North Carolina, who is overseeing a separate Senate Intelligence Committee probe, has also expressed an interest in getting to the bottom of what happened at the Trump Tower meeting.

Paul Manafort, campaign manager for Presumptive 2016 Republican Presidential Nominee Donald Trump, speaks during a Bloomberg Politics interview on the sidelines of the Republican National Convention (RNC) in Cleveland, Ohio, U.S., on Monday, July 18, 2016. The Senate Judiciary panel wants him to testify

Judiciary Chairman Sen. Charles Grassley has indicated he would be willing to subpoena Manafort and Trump Jr. if necessary. It was not immediately clear whether they would appear.

Mueller is investigating allegations by U.S. intelligence agencies that Russia interfered to help Trump win the presidency and possible collusion between Moscow and the Republican's campaign. Russia denies meddling in the campaign, and Trump says there was no collusion.

If Trump Jr. were to appear before the judiciary committee, he would be the highest member of the president's inner circle of relatives and White House aides to testify in Congress about the Russia allegations. Several congressional panels have investigations open.

Ike Kaveladze has been identified as the eighth person known to have attended a meeting with Donald Trump Jr.

The allegations have dominated Trump's first six months in office. Trump Jr., who runs the Trump Organization family business, released emails last week in which he eagerly agreed in June 2016 to meet a woman he was told was a Russian government lawyer who might have damaging information about Democratic election rival Hillary Clinton as part of Moscow's official support for his father's campaign.

The meeting in Trump Tower in New York appears to be the most tangible evidence of a connection between Trump's campaign and Russia, investigators in congress have said.

Grassley has said he would coordinate with Mueller to ensure that any witnesses the panel brings would not conflict with Mueller's criminal investigation.

Feinstein, asked whether Mueller had given the go ahead for Trump Jr. and Manafort to testify publicly, said, 'yes.'

Feinstein said the committee planned for the testimony to be part of a broader hearing scheduled for Wednesday but has now been postponed. She could not confirm whether the hearing would take place next week.

A man who works for a Moscow-based developer with ties to Trump was identified on Tuesday as the eighth person to attend the Trump Tower meeting.

Lawyer Scott Balber confirmed Ike Kaveladze's name to Reuters after CNN reported that his client had been identified by special counsel Mueller's prosecutors and was cooperating in their investigation.

Balber represented Trump himself in the New York businessman's 2013 lawsuit against comedian television host Bill Maher, demanding the $5 million Maher offered to give to charity if Trump could prove his father is not an orangutan.

Kaveladze's LinkedIn profile identifies him as vice president of Crocus Group, a company run by Moscow-based developers Aras Agalarov and his son, Emin, an Azerbaijani-Russian pop star. The two have ties to the Trump family and helped set up last year's meeting between Trump Jr. and Russian lawyer Natalia Veselnitskaya.

Kaveladze was asked to go to the meeting with the understanding that he would be a translator for Veselnitskaya, only to find she had brought her own translator with her, Balber told CNN.

Balber said he also represents the Agalarovs. Balber said Mueller's investigators have not interviewed his client or made contact about the Agalarovs.

In addition to Trump Jr., lawyer Veselnitskaya, her translator, and Kaveladze, the meeting was attended by Trump son-in-law Jared Kushner, Manafort, publicist Rob Goldstone and Russian-American lobbyist Rinat Akhmetshin.

Anatoli Samochornov was identified as Veselnitskaya's translator in multiple media reports.

In Moscow, Russia said it reserved the right to retaliate against the United States after a meeting in Washington ended without an agreement to return Russian diplomatic property the U.S. had seized.

Trump's predecessor President Barack Obama ordered the seizure of two Russian diplomatic compounds in New York and Maryland and the expulsion of 35 Russian diplomats in December over what he said was their involvement in hacking the U.S. election campaign.
