The Washington Post reported this week that Mueller is investigating whether Trump attempted to obstruct justice when he suggested Comey drop an FBI investigation into Michael Flynn, Trump's former national security adviser, as well as when he fired Comey.
Is there an investigation?
US Vice-President Mike Pence has hired a lawyer known for defending government officials in high-profile investigations to help him with probes into whether there were ties between the election campaign of President Donald Trump and Russian Federation. Last month, Rosenstein sent a memo to Trump raising concerns over FBI Director James Comey - concerns the White House then cited as a central reason for Comey's firing.
"I am being investigated for firing the FBI Director by the man who told me to fire the FBI Director!" He decried a "witch hunt" that he said is being "led by some very bad and conflicted people!" Pence headed the Trump transition until Inauguration Day.
United States intelligence agencies have concluded that Moscow interfered in the 2016 presidential campaign to try to tilt the vote in Trump's favour. According to the Post, Mueller plans to interview both officials soon, and also plans to question Richard Ledgett, who until recently held the No. 2 job at the NSA.
He was sacked by Trump on May 9.
President Trump's personal lawyer has retained a Washington, D.C. -based lawyer to represent him in the various government probes connected to Russian involvement in the 2016 election.
As for a Trump tweet on Friday - "I am being investigated for firing the FBI Director by the man who told me to fire the FBI Director!"
Comey was unabashed about accusing Trump and his administration of telling "lies", and said he began the practice of immediately making notes after talking with the president because "I was honestly concerned that he might lie" about the conversations. The intelligence committee is the lead congressional panel on the Russian Federation hacking scandal, including highly publicized hearings with fired FBI Director James Comey and Attorney General Jeff Sessions.
"His concern was, because we're looking at the potential - again, that's the subject of the investigation - coordination between the campaign and Russian Federation, because it was President Trump - President-elect Trump's campaign, this person's view was, inevitably, his behavior, his conduct will fall within the scope of that work", Comey said.
In a second tweet, he continued with "Crooked Hillary destroyed phones with hammer, "bleached" emails, and had husband meet with (Attorney General Loretta Lynch) days before she was cleared and they talk about obstruction?"
Meanwhile, the relationship between Rosenstein and Trump took another turn Thursday night when the Justice Department issued an unusual warning urging the public to "exercise caution" when it comes to anonymously sourced reports.
Separately, Coats testified before the Senate Intelligence Committee in a closed session Thursday that lasted for three-and-a-half hours.
"We do not know what this report refers to", Jamie Gorelick, Kushner's attorney, said in a statement to CNN. As Trump still struggles to acknowledge, the USA intelligence community is fully convinced that Russian Federation carried out an attack on our democracy.
