Lisa P. Marston appeals from the district court’s grant of summary judgment to *384 AT&T in Marston’s employment discrimination suit. We have reviewed the briefs and joint appendix and find no reversible error. Accordingly, we affirm substantially on the reasoning of the district court. Marston v. AT&T Corp, No. CA-02-516-3 (E.D.Va. Mar. 31, 2003). In addition, we hold that any claim that Marston was subjected to a retaliatory hostile work environment was waived by her failure to clearly raise the claim in district court. See Muth v. United States, 1 F.3d 246, 250 (4th Cir. 1993). We dispense with oral argument, because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

AFFIRMED
