Except as otherwise provided by law and subject to paragraph (2), the Attorney General, or the head of any other department or agency of the Federal Government with law enforcement responsibilities, shall expeditiously disclose to the Director of National Intelligence, pursuant to guidelines developed by the Attorney General in consultation with the Director, foreign intelligence acquired by an element of the Department of Justice or an element of such department or agency, as the case may be, in the course of a criminal investigation.

The Attorney General by regulation and in consultation with the Director may provide for exceptions to the applicability of paragraph (1) for one or more classes of foreign intelligence, or foreign intelligence with respect to one or more targets or matters, if the Attorney General determines that disclosure of such foreign intelligence under that paragraph would jeopardize an ongoing law enforcement investigation or impair other significant law enforcement interests.
