ORDER AND JUDGMENT *

Daniel Bryant Yazzie, Jr., appeals a district court’s denial of his motion to void his conviction and release him from custody. Exercising jurisdiction under 28 U.S.C. § 1291, we affirm.

In 2008, Yazzie was convicted of a federal crime. He did not appeal his conviction or sentence. In 2009, he filed a motion seeking to void his conviction, citing Fed. R.Civ.P. 60(b). Yazzie argued that the trial court lacked jurisdiction and was an improper venue, that the prosecuting attorney made fraudulent misrepresentations to the court, and that the prosecutor failed to join a necessary party. Determining that 28 U.S.C. § 2255 provides the “exclusive avenue for challenging a federal criminal conviction or sentence,” and that Yazzie’s motion could not properly be re-characterized as a § 2255 petition because it would be time-barred, the district court denied the motion. It later denied a subsequent, substantially identical motion for the same reasons, and denied Yazzie’s motion to proceed in forma pauperis (“IFP”). Yazzie timely appealed. 1

Yazzie has neither challenged the district court’s conclusion that § 2255 is an *969 adequate and effective remedy, nor challenged the district court’s decision that his motion should not be recharacterized as a § 2255 petition. Instead, he seeks to reassert his motion under Rule 60(b). However, Yazzie may not challenge his conviction and sentence under Rule 60(b) because “[t]he exclusive remedy for testing the validity of a [federal] judgment and sentence, unless it is inadequate or ineffective, is that provided for in 28 U.S.C. § 2255.” Johnson v. Taylor, 347 F.2d 365, 366 (10th Cir. 1965) (per curiam). 2

Construing his pleadings liberally, see Haines v. Kerner, 404 U.S. 519, 520-21, 92 S.Ct. 594, 30 L.Ed.2d 652 (1972), Yazzie’s second Rule 60(b) motion could be recharacterized as a petition for a writ of error coram nobis. But Yazzie is ineligible for a writ of error coram nobis because he is currently in custody for the conviction he seeks to challenge. See United States v. Torres, 282 F.3d 1241, 1245 (10th Cir. 2002) (“[A] prisoner may not challenge a sentence or conviction for which he is currently in custody through a writ of coram nobis.”).

We therefore AFFIRM the district court’s order denying Yazzie’s motion. Because he has failed to demonstrate “the existence of a reasoned, nonfrivolous argument on the law and facts in support of the issues raised on appeal,” DeBardeleben v. Quinlan, 937 F.2d 502, 505 (10th Cir. 1991), we DENY Yazzie’s motion to proceed IFP on appeal.
