Death row inmate, Manuel Valle, appeals the district court’s denial of his motion to stay his execution. Valle filed a complaint alleging violations of his constitutional rights on September 23, 2011, and he requests the court stay his execution so that his claims may be heard. Valle is scheduled to be executed today, Wednesday, September 28, 2011, at 4:00 p.m. Because Valle has not shown a substantial likelihood of success on the merits we affirm the district court.

Valle contends his execution will violate the Eighth and Fourteenth Amendments to the United States Constitution because he says he was denied clemency proceedings or alternatively was denied clemency itself without the benefit of a clemency investigation and clemency counsel. Valle previously litigated clemency claims in Florida state court, and the district court questioned whether the Rooker-Feldman 1 doctrine precluded review of Valle’s claims in federal district court.

We are not convinced that the Rooker-Feldman doctrine bars the exercise of jurisdiction here. “The Rooker-Feldman doctrine ... is confined to cases of the kind from which the doctrine acquired its name: cases brought by state-court losers complaining of injuries caused by state-court judgments ... and inviting district court review and rejection of those judgments.” Exxon Mobil Corp. v. Saudi Basic Indus. Corp., 544 U.S. 280, 284, 125 S.Ct. 1517, 1521-22, 161 L.Ed.2d 454 (2005). The doctrines of issue or claim preclusion may bar Valle’s clemency claims, but we are not convinced that dismissal is warranted for lack of jurisdiction.

Turning then to Valle’s motion to stay his execution, the district court concluded Valle failed to meet his burden of persua *689 sion. A prisoner moving to stay his execution bears the burden of showing:

(1) he has a substantial likelihood of success on the merits;

(2) he will suffer irreparable injury unless the injunction issues;

(3) the stay would not substantially harm the other litigant; and

(4) if issued, the injunction would not be adverse to the public interest.

DeYoung v. Owens, 646 F.3d 1319, 1324 (11th Cir. 2011) (citation omitted).

This court previously declined to stay Valle’s execution because Valle had not shown a substantial likelihood of success on the merits. Valle v. Sec’y Fla. Dep’t of Corrs., 654 F.3d 1266, 2011 WL 3925753, at *2 (11th Cir. 2011) (per curiam). We agree with and adopt the district court’s reasoning on this issue. A stay of Valle’s execution is not appropriate.

AFFIRMED.
