Three federal contractors lost an appeal with the U.S. Court of Appeals. The DC Circuit upheld a statute banning any one person who enters a federal contract from contributing to a political campaign or party from the time negotiations start to the end of the contract. The contractors argued the decision violates First Amendment and equal protection rights. Nick Townsend is counsel for Arnold and Porter's national security and public policy practices. He tells In Depth with Francis Rose that the decision leaves a few too many unanswered questions for federal contractors.
