In his Senate testimony last week, Comey said Trump requested loyalty from him and asked that he drop an investigation into former national security adviser Michael Flynn. "If there are other witnesses or subjects, we don't want them hearing what other people may have said about it".
Burr says the committee staff met with Johnson on Monday.
But Ruddy opened a new line of questions about Mueller's impartiality - the fact that Trump had considered Mueller for the Federal Bureau of Investigation director's job before he was named special counsel.
Ruddy said he had a conversation with the president last week, but that Mueller did not come up.
"You're creating a debate that's not happening", said House Majority Leader Kevin McCarthy on Tuesday morning, responding to a reporter's question about the rumor.
Democratic Senator Dianne Feinstein of California told Rosenstein, "It would be catastrophic", if Trump fired Mueller.
Deputy Attorney General Rod Rosenstein, who named Mueller to lead the investigation into whether the Trump campaign colluded with Russian Federation, testified there was no reason to dismiss him, and said that he alone has the authority to do so. Lindsey Graham of SC tried to clarify where that line for "good cause" was. "So nobody else in the department will have the authority to do that", said Rosenstein.
He then called on his cabinet colleagues to have their say in the presence of reporters, forgoing the usual routine of the press being escorted out after preliminary on camera remarks.
Rosenstein said that if he fired Mueller, he would be required to explain it in writing. Trump can rescind the regulation that establishes the burden of "good cause" for such a firing, or he could simply fire Rosenstein and install someone more to his liking. "If there were not good cause it wouldn't matter what anyone said". It's unclear whether the president could override those rules and order Rosenstein to fire Mueller.

That's when Chavez, Leblanc and Valenzuela concocted a plan to sell the company's avocados and pocket the cash themselves. In recent times, the company changed its policy and began to deliver the fruits directly to their customers instead.
"I know what we're investigating, and he does not", Rosenstein said to Sen.
If questions arise about what matters Sessions should stay away from, he said, a career official in Rosenstein's office is consulted. She asked whether he has seen "any evidence of good cause" to fire Mueller.
The discussion on Mueller's investigation came after some of Trump's closest allies - including one of his sons - began questioning whether the wide-ranging probe is becoming too political.
Speculation is swirling about whether President Donald Trump will remove special counsel Robert Mueller from his post. "Senator, I'm not going to follow any order unless I believe those are lawful and appropriate orders", Deputy Attorney General Rod Rosenstein said at a Senate hearing on Tuesday.
This immediately led to the "Saturday Night Massacre" with the resignations of the Attorney General Elliot Richardson and Deputy Attorney General William Ruckelshaus on October 20, 1973.
Schiff told MSNBC's "Morning Joe" on Tuesday that "I don't think the Congress would sit still and allow the president to pick his own investigator".
On Tuesday, Democrats and Republicans expressed concern about Mueller's fate and advised the president that he would be making a big mistake by firing him.
But Chris Ruddy, the CEO of Newsmax and a friend of the President who attended meetings Monday at the White House, was the one who revealed that the issue was being discussed.
