President Joe Biden speaks in the State Dining Room of the White House, October 7, 2023, in Washington.
CNN  — 

President Joe Biden over the last two days participated in a voluntary interview with special counsel Robert Hur as a part of his classified documents investigation, the White House announced Monday.

“The President has been interviewed as part of the investigation being led by Special Counsel Robert Hur,” White House counsel’s office spokesperson Ian Sams wrote in a statement Monday. “The voluntary interview was conducted at the White House over two days, Sunday and Monday, and concluded Monday.”

“As we have said from the beginning, the President and the White House are cooperating with this investigation, and as it has been appropriate, we have provided relevant updates publicly, being as transparent as we can consistent with protecting and preserving the integrity of the investigation,” Sams continued, referring additional questions to the Justice Department.

The interview marks the first major development in the case known to the public in months and stands in stark contrast to Biden’s predecessor. Former President Donald Trump never interviewed with special counsel Robert Mueller during the investigation into Russian interference in the 2016 election despite extensive negotiations over a potential interview. Trump currently faces criminal charges in two separate special counsel investigations, including one regarding his own handling of classified documents after he left the presidency in January 2021.

The interview comes months after Biden told CNN there had been “no such request and no such interest” for an interview with the special counsel in the investigation.

A spokesperson for Hur, who oversees the Justice Department’s probe into classified documents found at Biden’s home and former private office, declined to comment to CNN.

White House press secretary Karine Jean-Pierre declined to say Tuesday whether Biden answered all questions posed to him or invoked executive privilege during the interview.

“I’m just not going to go beyond what my colleague has shared. If you have any further questions, certainly I would refer you to Department of Justice or the White House counsel to ask any detailed information,” she said.

The interview was scheduled weeks ago, according to a person familiar with the matter. It came as Biden spent the three-day holiday weekend in Washington, a rare occurrence.

The decision to stay at the White House seemed fortuitous as war erupted in Israel but in reality, the choice to skip traveling to one of his Delaware homes was weeks in the making so the president could sit for the interview. Few people inside the White House were aware of the plans, and there was little indication to those who were working there this weekend that the interview was in the works.

On Saturday morning, the president woke up to urgent news from his senior advisers: Israel was under attack. He convened a meeting of his national security team at 8:15 a.m ET.

The hours that followed would be filled with a whirlwind of activity for Biden, as he received multiple briefings by his top national security advisers, got on the phone with world leaders, including Israeli Prime Minister Benjamin Netanyahu in the Oval Office, and addressed the nation from the State Dining Room.

The president had a light public schedule Sunday and Monday with no public events, and reporters were given relatively early notice that Biden would not have any public appearances. On Monday, the president met with administration officials about the fighting in Israel in the morning and spoke with allies in the afternoon.

Some of Biden’s closest advisers were spotted at the White House over the weekend, including chief of staff Jeff Zients and senior advisers Mike Donilon and Anita Dunn, who is married to Bob Bauer, the president’s personal attorney. The group huddled in the Treaty Room of the White House residence on Saturday to go over Biden’s planned remarks on Israel.

On Sunday, Biden remained out of public view, though he did speak with Netanyahu by telephone. His interview for the special counsel investigation went undetected by most of those in the building.

That evening, he hosted a barbeque for White House residence staffers that included live music. On Monday, he continued the interview – even as events in Israel occupied his agenda. Biden stayed out of the public eye, with the White House calling a lid before noon Monday.

Jean-Pierre also wouldn’t say whether the Biden administration requested the interview be postponed following Hamas’ attack on Israel over the weekend.

“He’s been very much focused on the issues of the … horrific events that we have seen in Israel, and, you know, the president is able to do multiple things at once, right?” she said. “As president he has to do multiple things at once, and that’s what you saw him do this weekend.”

Hur was appointed in January to investigate incidents of classified documents being found at Biden’s former Washington, DC, office and his Wilmington, Delaware, home. Upon announcing the investigation, Attorney General Merrick Garland laid out a timeline of the case that began with the Washington discovery in November 2022.

The National Archives informed a DOJ prosecutor on November 4 that the White House had made the Archives aware of documents with classified markings that had been found at Biden’s think tank, which was not authorized to store classified materials, Garland said.

The Archives told the prosecutor that the documents has been secured in an Archives facility. The FBI opened an initial assessment five days later, and on November 14, then-US Attorney John Lausch was tasked with leading that preliminary inquiry. The next month, on December 20, White House counsel informed Lausch of the second batch of apparently classified documents found at Biden’s Wilmington home, according to Garland’s account. Hours before the announcement of Hur’s appointment, a personal attorney for Biden called Lausch and informed him that an additional document marked as classified had been found at Biden’s home.

The documents were found “among personal and political papers,” according to a statement from the president’s legal team. The FBI later searched Biden’s Rehoboth Beach, Delaware, home in February and found no additional documents.

While Biden has not often commented on the case, he said in January that he was surprised to learn that classified documents were found in his former office.

“I was surprised to learn there were any government records that were taken there to that office,” Biden said in response to a reporter’s question at a news conference in Mexico City, where he was attending a trilateral summit with the leaders of Mexico and Canada.

He emphasized at the time that he did not know what was in the documents. As CNN previously reported, US intelligence memos and briefing materials that covered topics including Ukraine, Iran and the United Kingdom were among them, according to a source familiar with the matter. Biden didn’t know the documents were there, and didn’t become aware they were there, until his personal lawyers informed the White House counsel’s office, one source familiar with the matter told CNN.

The president said his attorneys “did what they should have done” by immediately calling the Archives.

“People know I take classified documents, classified information seriously,” Biden added, saying that the documents were found in “a box, locked cabinet – or at least a closet.”

After documents were found in his Wilmington home later in January, Biden said he was cooperating fully with the Justice Department. Biden added that the documents were in a “locked garage.”

“It’s not like they’re sitting out on the street,” he insisted when a reporter asked why he was storing classified material next to a sports car.
