Steve Bannon has reached an agreement with Special Counsel Robert Mueller to come in for an interview: Sources

The interview has not yet been scheduled, according to one source.

Bannon spent roughly ten hours behind closed doors with the House Intelligence Committee Tuesday. The panel also subpoenaed Bannon for testimony as part of its Russia investigation after he refused Tuesday to answer questions about his time working for Trump during the transition and in the White House.

Bannon, according to one source close to him, welcomes the subpoenas and hopes it sends a signal to the president that he is not seeking to spill information. Bannon parted ways with the president this month in wake of Michael Wolff's bombshell book, “The Fire and the Fury: Inside the Trump White House”, which paints a portrait of dysfunction in the White House, told in many parts from Bannon's viewpoint.

White House Press Secretary Sarah Sanders on Wednesday confirmed that Bannon’s attorney was in touch with the White House yesterday during his interview with the House Intelligence Committee, as he determined whether or not to answer members’ and staff questions.

“That's the same process that is typically followed,” Sanders said. “Sometimes they actually have a White House attorney present in the room, this time it was something that was relayed via phone and, again, was following standard procedure for an instance like this and something that will likely happen again on any other number of occasions not just within this administration but future administrations,” Sanders said.

A source familiar with Bannon’s appearance before the House Intelligence Committee on Tuesday said the White House had instructed Bannon not to answer questions about his time during the transition and the White House unless and until the committee and the White House can reach agreement on the proper scope of questioning in light of executive privilege concerns.

In a statement to ABC News, Bannon attorney William Burck said, "Executive privilege belongs to the President of the United States. It’s not Mr. Bannon’s right to waive it.”

Bannon is expected back before the House Intelligence Committee to resolve questions about his testimony and claims of privilege as early as Thursday, sources tell ABC News.

In the book, Bannon reportedly said "The chance that Don Jr. did not walk these jumos up to his father's office on the twenty-sixth floor is zero."
