It's official. The House Oversight and Government Reform Committee has filed suit against Attorney General Eric Holder. The committee is seeking a declaratory judgment to force him to turn over the documents that they are seeking in connection with their investigation into Operation Fast and Furious.
The full title of the case is Committee on Oversight and Government Reform, United States House of Representatives v. Holder. The case is filled in US District Court for the District of Columbia and the assigned case number is 1:12-cv-01332.
The Federal Court's database Pacer shows the case but not the associated documents for the case as of this morning. I assume we will be seeing that later.
The committee's website does not have any further information on the suit.
