OPINION

Kerry Dennison, a former employee of the Pennsylvania Department of Corrections, appeals from the order of the United States District Court for the Middle District of Pennsylvania denying his motion for a new trial of his claims of retaliation in violation of Title VII, the Free Speech and Petition clauses of the First Amendment to the United States Constitution, the Pennsylvania Human Relations Act, and the Pennsylvania Whistle Blowers Act. 1 The motion for a new trial alleged that the District Court erred by requiring his counsel to disclose an exhibit to the defense prior to Dennison’s closing argument, and by limiting Dennison’s presentation of evidence in support of his claims. We review these evidentiary rulings for an abuse of discretion. United States v. Sokolow, 91 F.3d 396, 402 (3d Cir. 1996). For the rea *973 sons explained by the District Judge in his thorough memorandum, we will affirm the judgment of the District Court.
