*621 ORDER DENYING CERTIFICATE OF APPEALABILITY

Steven A. Gilkey, an inmate appearing pro se, seeks to appeal from the district court’s denial of his federal habeas petition, 28 U.S.C. § 2241. Mr. Gilkey challenged the Kansas Parole Board’s (KPB) decision to deny him parole and to delay further parole consideration for three years. The district court also dismissed other claims without prejudice. He contends that the denial was based on improper considerations: his history of substance abuse and his disability which requires a back operation. According to Mr. Gilkey, the denial violates his rights under the Constitution and the Americans with Disabilities Act (ADA), 42 U.S.C. §§ 12101-12213. Mr. Gilkey sought state habeas relief, which the state courts denied. Gilkey v. Kan. Parole Bd., 147 P.3d 1096 (Kan.Ct.App. 2006) (Table).

A challenge to the execution of a state sentence is considered under 28 U.S.C. § 2241. See Montez v. McKinna, 208 F.3d 862, 865 (10th Cir. 2000). Under § 2241, a writ of habeas corpus may extend to a prisoner “in custody in violation of the Constitution or laws or treaties of the United States.” 28 U.S.C. § 2241(c)(3). To appeal from the denial of the petition, Mr. Gilkey needs a certificate of appeala-bility (COA). 28 U.S.C. § 2253(c)(1)(A). This requires that he make “a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2). He must demonstrate that the issues raised are debatable among jurists, or that jurists could conclude that the questions deserve further proceedings. Miller-El v. Cockrell, 537 U.S. 322, 327, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003).

After considering the district court’s resolution, and giving due deference to the state court’s resolution of the federal constitutional claims, Henderson v. Scott, 260 F.3d 1213, 1215 (10th Cir. 2001), we conclude that the resolution of Mr. Gilkey’s claims is not reasonably debatable. For substantially the reasons set forth in the district court’s order, 1 R. Doc. 18,

We DENY a COA and DISMISS the appeal.
