Comey testified last week that he also felt pressured to drop the Flynn probe.
Mueller is investigating Russian interference in USA elections and possible Russian ties to the Trump campaign.
"US President Donald Trump today appeared to confirm that he was being probed for firing the FBI chief and described it as a "witch hunt", as he asserted that there was no proof of his "collusion with the Russians" even after seven months of investigation". Trump is just "responding to what he's seeing the media in a way that he thinks is appropriate to talk to those people that put him in office", Sekulow said, denying that Twitter consumes any significant portion of Trump's time.
Attorney Steve Ryan says Friday that Michael Cohen plans on cooperating "in all governmental inquiries".
When it comes to policy, President Donald Trump has a decent record of at least pursuing his core campaign promises.
Subcommittee Chairman Lindsey Graham, R-S.C., titled the session "Concurrent congressional and criminal investigations: lessons from history". He has already been subpoenaed by the House intelligence committee.
Ryan is a former general counsel for the Senate's committee on governmental affairs.
She said Trump has "embarked on an effort to undermine anyone with the ability to bring any misdeeds to light" and the Senate shouldn't let that happen.
In other words: the slate of dirty tricks that US intelligence agencies say Russia's spy services pulled on the United States, including cyberattacks on elections systems and American political figures and some of their top aides.
The Post also reported that Mueller was looking into possible financial connections between Trump's son-in-law Jared Kushner, now a top White House adviser, and a Russian bank, as well as other financial dealings with Russia on the part of others in the Trump entourage.
Russia says Trump is using 'Cold War rhetoric' on Cuba
There is no doubt that if the United States wants to influence Cuba, the best policy is to engage more with Cuba, not disengage. By canceling Obama's Cuba deal, the Post reported, Trump could "neutralize a chief rival's ability to gain an early advantage".
On Thursday an aide to Vice President Mike Pence revealed he was hiring Richard Cullen - a veteran of the Iran-Contra investigation, Watergate and the 2000 vote recount in Florida - as a private lawyer.
Yet Trump's angry tweets on Friday underscored the near-impossible challenge his advisers and legal team have in trying to get him to avoid weighing in on an active investigation.
It was unclear what report or reports Rosenstein was referencing.
Trump s digital volley appeared to be trained at Deputy Attorney General Rod Rosenstein, who recommended the firing last month of James Comey - an nearly unprecedented move that could yet imperil Trump s presidency.
Oddly enough, Boente was acting deputy attorney general when Sessions recused himself, and until Rosenstein was appointed.
A person familiar with Trump's tweet said the President was referencing news reports that he is under investigation and was not indicating that he's been personally informed by the special counsel that he is a target of the probe.
Part of the revelations surrounding the Russian Federation investigation and the firing of Comey has been that Trump repeatedly pushed top intelligence officials to say in public that Trump was not personally under investigation and that there was no evidence of collusion between his campaign and Russian Federation in its interference in the 2016 election. "Witch Hunt" he tweeted from the White House shortly before leaving for Miami.
'Obsession': Trump's tweets come as Politico weighs in with another story saying that Trump aides are anxious that the president's "obsession" with the Russian investigation is consuming his presidency. "Regulations way down, jobs and enthusiasm way up!"
And he stood by his use of social media: "The Fake News Media hates when I use what has turned out to be my very powerful Social Media - over 100 million people!"
If Trump follows through on what it looks like he wants to do, he will set off a constitutional crisis the likes of which hasn't been seen in more than four decades.
Three members of the team he has hired so far have been reported to have made election donations to Democrats, a fact that has become another avenue of attack for Trump supporters.
Like many Trump tweets, it can be read both ways. Mueller is leading the ongoing investigation into Russian interference in the 2016 presidential election.
