The Washington Post reported June 15 that Mueller was expanding his investigation to include potential obstruction of justice charges for Trump during his conversations with Comey. "You can bet that when the president testifies regarding his role in Comey's firing, he will be asked about this tweet".
The Trump tweet indicated that he is under investigation and as a result, he is lashing out at the investigator, although he did not mention any particular investigator by name.
President Donald Trump says it's "sad" that seven months of investigations and hearings into possible links between his campaign and Russian Federation have been fruitless.
In light of Trump's concern about leaks, it's possible that Rosenstein's Thursday night statement was aiming to appease a president who has himself often criticized the news media for citing unnamed sources.
"The message the president is sending through his tweets is that he believes the rule of law doesn't apply to him and that anyone who thinks otherwise will be fired", Feinstein said in her statement.
That appeared to be the first public confirmation that Trump is being investigated for obstruction of justice - and a digital salvo trained at Deputy Attorney General Rod Rosenstein, who wrote a memo criticising Comey. "That's undemocratic on its face and a blatant violation of the president's oath of office".
A Justice official said Rosenstein was motivated in part because of frustration that recent news stories have unfairly brought on a torrent of "leak" accusations against the Federal Bureau of Investigation and Mueller's team.
Trump has told associates he has the legal authority to fire Mueller.
The president has long vehemently denied any collusion with Moscow. President Donald Trump's closest allies are attacking the integrity of those involved in the widening probe of Russian interference in the US election, accusing special counsel Mueller of driving a biased investigation.
If Rosenstein recuses himself, Brand, a Trump appointee, would become the top Justice official overseeing Mueller's work. The US president has denied trying to influence the investigation, but has acknowledged in an interview that Russian Federation was on his mind when he dismissed Comey.
Earlier this month, Rosenstein told The Associated Press that "if anything that I did winds up being relevant to his investigation then, as Director Mueller and I discussed, if there's a need from me to recuse, I will". An official of Trump's transition confirmed the lawyer's internal order, which was sent Thursday.
The president, while boarding Marine One on the White House South Lawn Friday morning en route to Miami ignored a reporter's question as to whether he still has faith in Rosenstein.
Gingrich's observations also came amid news reports of President Trump added another high-powered lawyer to his personal team and Vice President Mike Pence had hired his own personal lawyer.
Trump also lashed out at the media, on a day that aides hoped would be focused on his decision to undo some of Barack Obama's detente with Cuba.
