We affirm the district court’s dismissal of Counts’s suit for lack of subject matter jurisdiction for the following reasons:

1. We find no clear error in the district court’s determination that, under *625 Texas law, original defendant Edmundo Guevara was acting within the scope of his employment by the Federal Bureau of Investigation when he made the allegedly defamatory remarks that are the basis of this lawsuit. See Minyard Food Stores, Inc. v. Goodman, 80 S.W.3d 573, 577-79 (Tex. 2002).

2. Because Guevara was acting within the scope of his federal employment in making the remarks, the United States was properly substituted as a party in place of federal employee Guevara pursuant to the Federal Employees Liability and Reform and Tort Compensation Act of 1988 (Westfall Act). 28 U.S.C. § 2679(d)(1) — (2). Pursuant to the Westfall Act, upon substitution, the case fell under the Federal Tort Claims Act (FTCA) 28 U.S.C. § 2671 et seq.

3. The claimed defamatory conduct of federal employee Guevara falls within the “libel and slander” exception to the FTCA divesting the court of subject matter jurisdiction over the United States. 28 U.S.C. § 2680(h).

4. We note Appellants’ complaint of the district court’s conversion of the Government’s 12(b)(1) motion to dismiss to a Rule 56 motion for summary judgment. Because we find that the district court did not err in weighing the evidence related to the scope-of-employment issue under either standard, we do not reach this issue.

Affirmed.
