Special counsel Robert Mueller, who is overseeing the Department of Justice Russia investigation, is looking into whether President Trump attempted to obstruct justice, officials tell the Washington Post.
Former FBI director James Comey testified last week that soon after he was sacked in mid-May, he asked a friend to share the contents of a memo in which he described a conversation with President Trump that Comey had found troubling.
They say senior intelligence officials will be interviewed about whether Mr Trump tried to end an inquiry into his sacked national security adviser.
That isn't true anymore, according to reporting by The Washington Post on Wednesday night.
Former Homeland Security Secretary Jeh Johnson will testify in open session before the House intelligence committee as part of its investigation into Russian interference in last year's election campaign. If accurate, the report would also indicate Trump still has no understanding of the position the appointment of a special counsel has placed him in.
Kasowitz issued a statement saying the Federal Bureau of Investigation was behind the Post story and called the leak "outrageous, inexcusable and illegal".
"That's a decision that the president will make in consultation with his chief lawyer, Marc Kasowitz, and that the president said he'll address next week", he said.
This marks a dramatic turn by Robert S Mueller III in the investigation, now nearly a year old.
Trump, we know now, repeatedly asked then-FBI Director James Comey whether he, personally, was under investigation. Susan Collins, R-Maine, Rosenstein said, "Senator, I'm not going to follow any order unless I believe those are lawful and appropriate orders". "Officials say that changed shortly after Comey's firing".
Deputy Attorney General Rod Rosenstein, who appointed Mueller last month, testified Tuesday he has seen no evidence of good cause to fire Mueller.
His comments came just days after explosive comments by ousted FBI director James Comey to the same committee, suggesting that Trump sought to interfere with the investigation.
On Tuesday, Attorney General Jeff Sessions declined to reveal what he and Trump have discussed about the Russian Federation probe or the decision to fire Comey. In an interview on CNN's "New Day", Ruddy said, "I think it is a consideration the President has had because Mueller is illegitimate as special counsel". Susan Collins, R-Maine, asked Rosenstein during an open Senate Appropriations subcommittee hearing what he would do if Trump asked him to fire Mueller.
The Senate panel also plans to hear at some point from Jared Kushner, Trump's son-in-law and one of his closest White House aides.
