WASHINGTON — U.S. officials have offered to brief congressional leaders on their investigation into the classified documents found at former President Donald Trump’s Florida residence as well as President Joe Biden’s Delaware home and former private office, people familiar with the matter said Sunday.

A briefing could come as soon as this week. But it may not meet demands from lawmakers who want to review the documents taken not just from Mar-a-Lago but also from the locations belonging to Biden and the Indiana home of former Vice President Mike Pence.

Six months after federal agents first conducted an unprecedented search of a former president’s home for classified documents, the White House faces bipartisan pressure to share what it found with lawmakers who say they are concerned about the potential damage to national security and intelligence sources. Separate special counsels are investigating the documents found in the possession of Trump and Biden.

Officials have declined to answer most questions in public or private about what they found, citing the ongoing criminal investigations and a separate “risk assessment” of the possible damage to intelligence sources.

Rep. Mike Turner, who heads the House Intelligence Committee, told NBC’s “Meet the Press” on Sunday that the administration notified him it would brief on the documents this week.

“This administration needs to understand we do have national security urgent matters,” said Turner, R-Ohio. He also called on the White House to brief him on the Chinese balloon shot down Saturday.

“What’s interesting is that the moment this balloon became public, I got a notice not from the administration that I’m going to get a briefing on this balloon, but they have to rush to Congress now to talk to us about Donald Trump’s documents,” he said, adding that a discussion of Biden and Pence’s records was expected to be included.

Three people familiar with the matter confirmed a congressional briefing was offered to the “Gang of Eight” — the Republican and Democratic leaders of the House and Senate and of both intelligence committees. The people spoke on condition of anonymity to discuss intelligence matters.

Any briefing is not expected to include direct access to the documents that were seized, the people said.

Sens. Mark Warner, D-Va., and Marco Rubio, R-Fla., the chairman and vice chairman of the Senate Intelligence Committee, asked for that access in a letter last week to Attorney General Merrick Garland and Director of National Intelligence Avril Haines.

The director of national intelligence’s office and Department of Justice both declined to comment Sunday.

The Justice Department says roughly 300 documents with classified markings, including at the top-secret level, have been recovered from Mar-a-Lago after being taken there after Trump left the White House. Last August, FBI agents executed a search warrant at the property after developing evidence that led them to believe that Trump and his representatives had not returned all the classified files.

The material taken at that time included roughly 13,000 government documents, including about 100 bearing classification markings. Some of the material was so sensitive that Justice Department prosecutors and FBI counterintelligence investigators required additional security clearances to review them.
