While a sitting president is unlikely to face criminal prosecution, obstruction of justice could form the basis for impeachment.
Grassley on Tuesday stopped short of ruling out establishing a congressional investigation into the question of whether Trump obstructed justice. At the end of May, the chief of the Justice Department's Fraud Section, Andrew Weissman, also joined the team, NPR's Carrie Johnson reported at the time.
Sessions, a close campaign adviser to Trump and the first senator to endorse him, stepped aside from the investigation in early March after acknowledging he had spoken twice in the months before the election with the Russian ambassador.

Then, according to Entous's sources ("officials" familiar with Coats's description of what happened), Trump "started complaining about the FBI investigation and Comey's handling of it".
"I personally think it would be a very significant mistake", Ruddy said.
Mr Trump's legal team quickly denounced the report.
They claimed a few days after the March 22 meeting, Mr Trump spoke separately with Mr Coats and Mr Rogers and asked them to issue public statements to the effect that there was no evidence of coordination between his campaign and Russian Federation.
Both Fleischer and Gingrich had previously vouched for the character and integrity of Mueller, who was appointed Federal Bureau of Investigation director by Bush and whose term was extended an extra two years by Democratic President Barack Obama.
Following the Post's report, Trump's outside attorney slammed the FBI for releasing information about the ongoing investigation.
But testifying in the Senate Tuesday, Rosenstein said he is confident that Mueller will have "the full independence he needs" to investigate thoroughly. The president has accused Comey of lying about those encounters.
The report stated that Trump was angered when he learned of the relationship and made plans to dump Mueller before being convinced it would be a disastrous move.
Mr. Trump has said he is "100 per cent" willing to testify under oath on Mr. Comey meetings and tell the FBI Special Consul Robert Muller that he never asked FBI to stop investigating. The difference here is that, so far as we know, Coats refused to carry out Trump's request. But if he tries to sack the special counsel, he will be making a bet that the country is too weak and disoriented to stand together behind its constitutional structure of law - which, really, would be the saddest outcome of all.
Mueller spokesman Peter Carr told NPR's Carrie Johnson, "We'll decline to comment".
Per the Post, Mueller has chose to continue that investigation.
Trump interviewed Mueller for the director's position days before Rosenstein picked Mueller as special counsel for the Russian Federation probe, Sanders confirmed Tuesday.
"We also were aware of facts that I can't discuss in an open setting that would make his continued engagement in a Russia-related investigation problematic", Comey said. The President has stressed he was not under investigation, and has taken to Twitter to dismiss the entire investigation as a hoax.
The Post reported the scope of the probe expanded to include Trump shortly after Comey's dismissal, citing government officials.
