Reports say the president's former chief strategist struck a deal wednesday to answer questions directly from Special Counsel Robert Mueller's team. "This is part of a judicially recognised process that goes back decades", Ms Sanders told reporters. Burck is also representing McGahn in special counsel Robert Mueller's investigation into contacts between the Trump campaign and Russian Federation.
Since the White House briefing Wednesday afternoon, the White House counsel and the committee have spoken again.
"We'll hope to get a different answer back from his counsel after they consult with the White House because the position they took yesterday is completely unsustainable", Schiff said.
Bannon confirmed that he had received the subpoena from Mueller during his House Intelligence Committee interview, according to a person who spoke to the AP on condition of anonymity because the person wasn't authorized to publicly discuss Bannon's interactions with Mueller.
The reports show a shift from Bannon's handling of a congressional investigation into the possible collusion. He never served in the White House.
Then, hours into Bannon's closed door testimony, Bannon's lawyers informed the White House from Capitol Hill that the questions would extend beyond the scope of what the White House understood the agreement to be.
The White House replied and told Bannon's lawyer which questions he should and shouldn't respond to.
Bannon reportedly refused to answer questions, citing executive privilege, which allows presidents to keep some information about their discussions and deliberations private.
Judge Andrew Napolitano said Steve Bannon will be entering a "very risky environment" when he interviews with Special Counsel Robert Mueller's team.
However, he added that it was unusual for a subpoena to be issued if Mr Bannon had been open to an interview and may suggest a reluctant witness wanting to demonstrate his hand had been forced.
He said the committee expects to have Bannon return for more questioning. Formally asserting executive privilege could be embarrassing for the White House, which has insisted it has nothing to hide in the ongoing Russian Federation investigation and that it is cooperating fully.
At that point, House Intelligence Committee Republicans and Democrats joined forces to issue Bannon a subpoena on the spot to compel his testimony.
Conaway and Schiff instructed Bannon to be prepared by Thursday "to answer all questions for which there has been no claim of privilege asserted" and to "work with the White House to expeditiously clarify the precise scope of any executive privilege claims the president may wish to invoke", according to a letter obtained by The Washington Post.
Lewandowski would not discuss whether Trump talked to him about his testimony, for instance, Schiff said. "And no effort to hide behind a later potential invocation of privilege by the executive", Schiff said.
Last week, the publication of Michael Wolff's "Fire and Fury: Inside the Trump " caused a major public spat between him and the.
Russian Federation denies any attempt to interfere and Trump has denied any collusion. Lawmakers questioned Bannon on Trump's firing of former FBI Director James Comey, although Bannon was not present when that decision was made.
