An event reportedly of particular interest to Mr Mueller is an exchange on March 22, when Mr Coats told associates that Mr Trump had asked him to intervene with Mr Comey to get him to back off the president's former national security adviser Mike Flynn as part of the Federal Bureau of Investigation probe into the Russian Federation affair.
The friend to President Donald Trump who claimed the President is considering firing the special counsel leading the FBI investigation into Russia's role in the 2016 election stood by his remarks Tuesday, adding that he believes special counsel Robert Mueller is "illegitimate".
"It makes sense to point out any level of bias, to highlight any biases inherent in Mueller and this probe in order to force him to be transparent", Gingrich said.
White House frustrations with the Justice Department spilled into public view last week, when Trump on Twitter criticized the legal strategy in defending his proposed travel ban. Doubt, however, has been cast on that explanation because of cryptic testimony from former FBI Director James Comey last week.
"I think he is considering perhaps terminating the special counsel", Ruddy, who leads the conservative news website Newsmax, said on PBS NewsHour.
They say Trump did not collude with Russian Federation and see the investigation as a politically motivated sham that handicaps Trump's ability to execute his agenda, according to one person who advises the White House on how to handle the probe.
A spokesman for Mr Mueller's team declined to comment on Wednesday.
Since being appointed special counsel in May, Mueller has built a team of formidable legal minds who've worked on everything from Watergate to Enron.
Those questions were prompted after a friend of President Donald Trump said the White House was considering firing Mueller. He plans to interview three Trump administration officials to study possible obstruction of justice, multiple newspapers reported. Ruddy agrees that the move would be a wrong move, but dismissed the investigation Mueller is overseeing.
While Rod Rosenstein, the deputy attorney general, has not said what exactly prompted him to appoint Mueller, his decision came after The New York Times published details about an Oval Office meeting Comey had with the president in February.
Rosenstein's letter critical of Comey's handling of the Hillary Clinton email server investigation served as the Trump White House's first reasoning for firing Comey - though Trump later undercut that explanation by saying he fired Comey in hopes of ending the Russian Federation probe. Still, Gingrich said any special counsel with an agenda can "all of the sudden find something procedural and technical to latch onto". Rosenstein would be the one to fire Mueller, which he repeatedly assured senators Tuesday he would not consider without "good cause". "Newt, whatever you think you're getting in return for obsequiously sliming an American hero, I guarantee you it's not worth it. Stop". Ruddy never spoke to the President regarding this issue.
"He is being advised by many people not to do it", the source said. Atty. Gen. Jeff Sessions has recused himself from the investigation and is testifying Tuesday before the Senate Intelligence Committee. "I don't question his integrity at all, but he has to be careful not to create the impression of partiality".
