The Texas Association of Business (TAB) and William O. Hammond appeal *713 the district court’s dismissal of their complaint for lack of jurisdiction. They argue that the district court erred in determining that the complaint did not allege facts establishing an actual case or controversy as they have been threatened with lawsuits and a criminal investigation concerning their creation and publishing of issue-oriented advertisements discussing the records of various candidates for the 2002 Texas elections. Because TAB and Hammond have not alleged that the threat of litigation is fairly traceable to the challenged action of the defendants, they have not met their burden to establish that an actual case or controversy exists. See Lujan v. Defenders of Wildlife, 504 U.S. 555, 560-61, 112 S.Ct. 2180, 119 L.Ed.2d 351 (1992).

AFFIRMED.
