Special counsel Robert Mueller has brought 13 lawyers on board to handle the Russia investigation, with plans to hire more, according to his spokesman Peter Carr.
Mueller has assembled a high- powered team featuring top investigators and leading experts in the nation. It includes seasoned attorneys who worked on cases ranging from Watergate to the Enron fraud scandal, and have represented major American companies in court.
They include James Quarles and Jeannie Rhee, whom Mueller brought over from his old firm,
WilmerHale. He's also hired Andrew Weissmann, who led the Enron investigation.
Former independent counsel Kenneth Starr, who investigated President Bill Clinton in the 1990s, described it as a "fantastic team."
"That is a great, great team of complete professionals, so let's let him do his job," Starr told ABC News.
But while only five attorneys have been identified, concerns have come up over the political leanings
of Quarles, Rhee and Weissmann, who've donated to the Democrats
, according to a CNN analysis of Federal Election Commission records.
The special counsel's investigators are looking into questions of Russian interference in last year's election and plan to speak to senior intelligence officials, a source familiar with the matter told CNN.
Mueller is also investigating whether President Donald Trump attempted to obstruct justice, The Washington Post
The Post has reported
that the interviews represent a widening of the probe to include a query into whether the President obstructed justice in suggesting to his former FBI Director James Comey that he drop the investigation into Michael Flynn, Trump's former national security adviser, as well as for firing of Comey.
Mueller's investigators have asked for information and will talk to Director of National Intelligence Dan Coats and National Security Agency Director Adm. Mike Rogers, according to a source, who said they have also sought information from recently retired NSA Deputy Director Richard Ledgett. Coats and Rogers have testified that they were not pressured by the Trump administration.
The interviews are some of the first indications of the efforts of Mueller's newly assembled team.
Ultimately, it would be up to Mueller to decide whether there is enough evidence to recommend pursuing charges on any part of the investigation
Law enforcement sources tell CNN that the special counsel is gathering information and considering whether there is evidence to launch a full-scale obstruction investigation.
Trump, however, referred to the Post's reporting as a "phony story" in a tweet Thursday morning.
"They made up a phony collusion with the Russians story, found zero proof, so now they go for obstruction of justice on the phony story. Nice," the President tweeted
In another tweet Thursday, Trump called it "the single greatest WITCH HUNT in American political history — led by some very bad and conflicted people!"
A spokesman for the office of the special counsel declined to comment, and so did one for the Director of National Intelligence. In a statement, the National Security Agency said it "will fully cooperate with the special counsel," but declined to comment further.
Mark Corallo, a spokesman for Trump's outside attorney, Marc Kasowitz, slammed the Post's reporting. "The FBI leak of information regarding the President is outrageous, inexcusable and illegal," he said.
