When directed to do so pursuant to section 288b(b) of this title, the Counsel shall bring a civil action under any statute conferring jurisdiction on any court of the United States (including section 1365 of title 28), to enforce, to secure a declaratory judgment concerning the validity of, or to prevent a threatened failure or refusal to comply with, any subpena or order issued by the Senate or a committee or a subcommittee of the Senate authorized to issue a subpena or order.
(b) Actions in name of committees and subcommittees
Any directive to the Counsel to bring a civil action pursuant to subsection (a) in the name of a committee or subcommittee of the Senate shall, for such committee or subcommittee, constitute authorization to bring such action within the meaning of any statute conferring jurisdiction on any court of the United States.
