In a letter to the National Archives, Mr. Biden’s White House counsel, Dana Remus, said Mr. Biden had rejected Mr. Trump’s claims that the visitor logs were subject to executive privilege and that “in light of the urgency” of the committee’s work, the agency should provide the material to the committee within 15 days.

Mr. Biden had similarly decided last year not to support Mr. Trump’s claim of executive privilege over other batches of White House documents and records sought by the committee. Mr. Trump went to federal court to block the release of those earlier batches but lost.

Citing in part the same reasoning as in the earlier case, Ms. Remus told the National Archives that the documents needed to be disclosed in a timely fashion because “Congress has a compelling need.” She said that “constitutional protections of executive privilege should not be used to shield, from Congress or the public, information that reflects a clear and apparent effort to subvert the Constitution itself.”
