Following a jury trial, Daniel Watts, Louisiana prisoner # 437719, was convicted of attempted second-degree murder and sentenced to 50 years in prison. After his 28 U.S.C. § 2254 petition was dismissed as untimely, he filed a 28 U.S.C. § 2241 petition challenging his conviction. The district court construed this motion as an unauthorized successive § 2254 petition and transferred the matter to this court. The district court’s transfer order is an appealable collateral order over which this court has jurisdiction. See In re Bradford, 660 F.3d 226, 228-29 (5th Cir. 2011); see also United States v. Fulton, 780 F.3d 683, 688 (5th Cir. 2015).

Watts argues that the district court erred by construing his § 2241 petition as a successive § 2254 application. According to Watts, he was convicted of an illegal, nonresponsive verdict, and,' as such, he asserts that he is not challenging his conviction under § 2254 because there is no valid conviction to challenge.

As the record shows, Watts’s petition challenges the validity of the same Louisiana conviction for attempted second-degree murder that was the subject of his first § 2254 petition, and this challenge could have been raised in that petition. See Leal Garcia v. Quarterman, 573 F.3d 214, 222 (5th Cir. 2009); In re Cain, 137 F.3d 234, 235 (5th Cir. 1998). Therefore, the district court properly construed the petition as a successive § 2254 petition, over which it lacked jurisdiction, and transferred it to this court. See Felker v. Turpin, 518 U.S. 651, 662, 116 S.Ct. 2333, 135 L.Ed.2d 827 (1996); United States v. Key, 205 F.3d 773, 774 (5th Cir. 2000). Accordingly, we AFFIRM the district court’s transfer order.
