    Before NEWMAN, Circuit Judge, FRIEDMAN, Senior Circuit Judge, and RADER, Circuit Judge.
   RADER, Circuit Judge.

The Merit Systems Protection Board affirmed the Department of Homeland Security’s removal of Mr. Patrick N. Sweeney from his position of Criminal Investigator (GS 1811-13). Because the record shows that Mr. Sweeney did not obey a direct order, substantial evidence supports the Board’s decision and, therefore, this court affirms.

I

Mr. Gene D. Lowery, Assistant Special Agent in Charge for National Security, Division One, supervised Mr. Sweeney. Before transfer to Mr. Lowery’s division, Mr. Sweeney had undergone a fitness-for-duty exam to recover his firearm due to a “public safety issue.” Specifically, Mr. Sweeney’s supervisors believed the fitness exam necessary because of improper requests for phone records of a prior supervisor, harassment of a fellow employee with numerous phone calls “at all hours of the night and day” when that employee refused to testify in a lawsuit, attempts to obtain a supervisor’s home address, and claims of a “conspiracy” against him by management.

In the face of a direct order, Mr. Sweeney refused to sign the Authorization for the Release of Medical Records in advance of the examination. Mr. Lowery recommended Mr. Sweeney’s removal for refusing to obey a direct order. The agency terminated Mr. Sweeney on March 10, 2006. The Merit Systems Protection Board (M.S.P.B.) affirmed the agency’s action.

II

This court must affirm any agency action, findings, or conclusions unless they are: (1) arbitrary or capricious, an abuse of discretion, or otherwise not in accordance with the law; (2) obtained without procedure required by law, rule, or regulation having been followed; or (3) unsupported by substantial evidence. 5 U.S.C. § 7703(c) (1996); Hayes v. Dep’t of the Navy, 727 F.2d 1535, 1537 (Fed.Cir.1984). This court examines the record for “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Brewer v. United States Postal Serv., 227 Ct.Cl. 276, 647 F.2d 1093, 1096 (1981) (quoting Consol. Edison Co. v. NLRB, 305 U.S. 197, 229, 59 S.Ct. 206, 83 L.Ed. 126 (1938)).

The Board found that Mr. Sweeney’s misconduct warranted termination. Mr. Sweeney maintains that the direct order to sign the medical release form violates 45 C.F.R. § 164.508, the Health Insurance Portability and Accountability Act (HIPAA), and 5 U.S.C. § 552(a), the Privacy Act. With respect to Mr. Sweeney’s HIPAA claim, HIPAA does not provide a private cause of action and clearly authorizes employers to require disclosure of medical records in connection with a fitness exam. 45 C.F.R. § 164.512(b)(l)(v). With respect to the Privacy Act claim, Mr. Sweeney even admitted that the Department of Homeland Security had the authority to order him to undergo the fitness exam.

Mr. Sweeney filed a complaint with the Office of Special Counsel alleging, among other things, an inappropriate relationship between one of his supervisors (Mr. Stephen Coffman) and the daughter of an indicted child pornographer. Mr. Sweeney contends that his termination is improper retaliation for “whistleblowing” activities protected by the Whistleblower’s Protection Act. 5 U.S.C. § 1211 et seq. The administrative law judge (AJ) found no retaliatory motive for the termination. The AJ determined that, even if the protected whistleblowing disclosures had not occurred, the agency would have still taken the same action. 5 U.S.C. § 1221(e)(2); 5 C.F.R. § 1209.7(b); Marano v. Department of Justice, 2 F.3d 1137, 1141 (Fed.Cir.1993).

Mr. Sweeney contends that the AJ erred in determining witness credibility. This court can overturn an AJ’s decision regarding credibility only if it is “inherently improbable or discredited by undisputed evidence or physical fact.” Dittmore-Freimuth Corp. v. U.S. 182 Ct.Cl. 507, 390 F.2d 664, 685 (1968). Credibility determinations are virtually unreviewable. Hambsch v. Dept. of the Treasury, 796 F.2d 430, 436 (Fed.Cir.1986). Accordingly, this court perceives no basis on this record to disturb the AJ’s credibility determinations.

Mr. Sweeney also alleges violations of his Fourteenth Amendment rights of due process and equal protection. He asserts that the administrative law judge engaged in extra-judicial conduct and exhibited bias. The record provides no basis at all for these claims. Because substantial evidence supports the Board’s decision affirming the Department of Homeland Security’s removal of Mr. Sweeney, this court affirms.
