Christopher Wray, a former top Justice Department official who Trump nominated for the FBI post in June, repeatedly indicated that he was not up to date on the latest revelations about the meeting.

Graham proceeded to read excerpts of the email chain between Donald Trump Jr. and Rob Goldstone, an entertainment publicist who represents Russian pop star and businessman Emin Agalarov, setting up the meeting before the presidential election.

The lawyer, Natalia Veselnitskaya, is said to be connected to the Russian government, though she has denied it.

When asked by Graham if Trump Jr. should have taken the meeting, Wray replied, “I'm not really in a position to speak to it.”

Asked the same question regarding a hypothetical scenario, Wray responded, “I would think you'd want to consult with some good legal advisers before you did that.”

Further pressed by Graham on whether the FBI would want to know about an effort by a foreign government to offer disparaging information about a political opponent, Wray said, “Any threat or effort to interfere with out elections by any nation state or any non-state actor is something the FBI would want to know.”

When asked whether Trump Jr.'s account of the meeting's arrangement was accurate, Wray again answered that he didn't "have the full context.”

Graham told Wray that he wanted him to review the email chain, which he described as Trump Jr.'s "email problems," and get back to the committee on his assessment of it.

The revelations about the meeting, which occurred on June 9, 2016, at Trump Tower, have fueled speculation about the possibility that there was collusion between Trump campaign associates and Moscow amid Russia's interference in the election.

Trump Jr. has said that the lawyer offered no damaging information on Clinton during the meeting. During a Fox News interview on Tuesday night, Trump Jr. acknowledged that he would have "done things a little differently" in retrospect.

Wray, who said that he has no reason to doubt the intelligence community's conclusions about Russia's election interference, said that such an effort is an "adversarial" act.
