Given that kind of support, a Democratic lawmaker, Ted Lieu, taunted the White House over the Mueller-firing chatter: "Double dare exists".

The investigation into Trump started after former FBI Director James Comey was sacked, according to the Washington Post report.

Trump creates his own version of normal.

Comey had previously assured Trump he was not under investigation.

Asked whether Trump's actions rose to the level of obstruction of justice, Comey testified last week: "I don't know".

Firing Mueller would most likely be a political disaster for Trump.

While he had recused himself from the Russian Federation probe, Sessions said, "I did not recuse myself from defending my honor against scurrilous and false allegations".

Mr. Coats and Adm. Rogers told a Senate panel on June 7 that they didn't feel pressured by Mr. Trump to intervene with Mr. Comey or to push back against allegations of possible collusion between the Trump campaign and Russian Federation during the 2016 presidential campaign. Truly, we don't know.

Trump is not the only one under scrutiny, Barrett said: Investigators are also looking into the finances of Trump associates.

Trump's behavior in office has been disruptive, to put it mildly.

Attorney and former FBI Director Robert Mueller, right, arrives for a court hearing at the Phillip Burton Federal Building in San Francisco, Thursday, April 21, 2016. If so, this crippling scandal could veer into a much more unsafe phase of presidential lawlessness. He described Mueller as operating independently from the Justice Department in his investigation. "But it wouldn't surprise me at all, even though it would be absolutely astonishing were he (Trump) to entertain this".

Goldsmith proceeded to analyze what would happen if Trump did the unthinkable.

"I think it's pretty clear based on what one of his lawyers said on television recently".

Statements made by Trump's friend Christopher Ruddy set off many new questions Monday night. So do the others, given Mueller's reputation for probity.

In an interview Tuesday morning on CBS, Gingrich said Trump is confident that Mueller will find he did nothing wrong.

This apparent effort to lay the groundwork for Mueller's firing raises a key question: Could the president do it?

Rosenstein, who has the sole ability to fire Mueller given that Attorney General Jeff Sessions has recused himself from matters relating to the investigation, told the panel he had seen no evidence of good cause for letting Mueller go and that he would not follow any theoretical order to fire him absent such evidence. Fears that Rosenstein might be ordered to dismiss Mueller had cropped up before Thursday as well.

Investigators will also look for any statements the president may have made publicly and privately to people outside the government about his reasons for firing Comey and his concerns about the Russian Federation probe and other related investigations, people familiar with the matter said.

This gets to the heart of the matter. He expressed concern that the public is losing trust in institutions put in place to handle the investigation.

Another talk-radio Trump booster, Laura Ingraham, who was rumoured to have been considered for a White House position, directed her followers to a story in a conservative newspaper that suggests Mueller might be tainted.
