Senate Judiciary Committee Chairman Chuck Grassley wrote a letter to secretary of Homeland Security John Kelly and Secretary of State Rex Tillerson asking how the Russian attorney who met with President Donald Trump a year ago was allowed in the country.
A spokesman for Grassley said Wednesday afternoon that Grassley was working with Mueller to ensure that any plans to question Manafort don't conflict with any criminal investigation, and that if conflicts do exist, the senator will "work to find a way for the committee to proceed with its oversight responsibility".
In a statement Tuesday, Trump's eldest son said he was posting the emails "in order to be totally transparent".
Trump Jr. on Tuesday morning posted a series of emails between himself and Rob Goldstone, a music publicist who contacted Trump Jr. and told him about an opportunity to receive potentially damaging information about Clinton as part of a Russian government effort to help his father's campaign.
His panel is investigating Russian meddling in the USA election. Trump Jr. responds: "I love it".
In response to calls for him to testify before the intelligence panel, Trump Jr. tweeted Monday that he was "happy to work with the committee to pass on what I know".
In the emails, Trump Jr. was told by an interlocutor that he could get "very high level and sensitive information" that was "part of Russian Federation and its government's support for Mr. Trump". The Russian lawyer has claimed that the 30-minute meeting focused on the Magnitsky Act and the issue of Russian adoptions by USA citizens.

Still, he was pleased to hear that the leaders of the Iraqi Security Forces were only willing to accept unconditional surrender. Iran, a key ally of Abadi's Shiite-led government, gave its congratulations too and offered help in rebuilding.
"I think many people would have held that meeting", Trump told Reuters. "Which is a very interesting point".
US intelligence agencies have blamed the Russian government for meddling through hacking in last year's election to benefit Trump and harm Hillary Clinton, his Democratic opponent.
The president's attorney, Jay Sekulow, said in an interview with NBC's "Today" that Trump Jr. did not violate any laws by accepting the meeting. The Iowa Republican says he wants Trump Jr.to appear "pretty soon", and it could be as early as next week.
Aside from concerns about Manafort's legal woes, Grassley said it "obviously would be appropriate" for members of the 15-person committee to question Manafort about his role in a June 9, 2016, meeting with a Russian lawyer; Trump's son-in-law and senior adviser Jared Kushner; and the president's son, Donald Trump Jr.
"In retrospect I probably would have done things a little differently", Trump Jr. said.
Still Trump remains defiant.
