President Biden’s White House plans to err on the side of disclosure given the gravity of the events of Jan. 6, according to two people familiar with discussions who, like others, spoke on the condition of anonymity to describe the private discussions.

In response to questions about White House deliberations over what information to release, Biden spokesman Michael J. Gwin said the president views the attack on the Capitol as “a dark stain on our country’s history” and is “deeply committed to ensuring that something like that can never happen again, and he supports a thorough investigation.”

Members of the investigative committee argue that Trump no longer enjoys the protection of executive privilege, encouraging the White House to push aside institutional concerns about sharing information with Congress and aid the panel in an investigation focused on what Democrats and a handful of Republicans have called an assault on democracy.

“It’s not really relevant because there’s no president involved — there’s no such thing as a former president’s executive privilege,” said Rep. Jamie B. Raskin (D-Md.), a committee member who teaches constitutional law. “That’s extremely dilute and not really relevant.”
