Washington (CNN) Top officials at the Justice Department, the FBI and the Office of the Director of National Intelligence agreed Monday to share highly classified information with lawmakers related to the Russia investigation amid an escalating controversy over the bureau's use of a confidential intelligence source during the 2016 presidential campaign.

White House press secretary Sarah Sanders said Monday that chief of staff John Kelly planned to "immediately" schedule a meeting with the officials and leaders of Congress to "review highly classified and other information they have requested."

But the statement -- vague enough to allow each side to claim victory -- did not fully settle the critical issue: whether the Justice Department would ultimately be forced to turn over the documents subpoenaed by House Intelligence Chairman Devin Nunes on the FBI source.

Sanders had said earlier that Deputy Attorney General Rod Rosenstein, FBI Director Christopher Wray and Director of National Intelligence Dan Coats were expected to gather at the White House on Monday afternoon for a discussion aimed at addressing congressional requests.

Rosenstein, Wray and several other officials were spotted leaving the White House just before 4 p.m. ET after over an hour inside. The Justice Department did not comment on the meeting or details of the agreement.
