Former prisoner Curtis Glinsey appeals the district court’s denial of his petition for writ of coram nobis. In 1998, Glinsey pleaded guilty to three counts of illegally acquiring and redeeming food stamps and one count of witness tampering (for plotting to have a witness killed). Glinsey’s direct appeal of his conviction, sentence, and restitution order resulted in an affir-mance, 1 and certiorari was denied. United States v. Glinsey, 209 F.3d 386 (5th Cir.), cert. denied, 531 U.S. 919, 121 S.Ct. 282, 148 L.Ed.2d 203 (2000). Thereafter, Glin-sey filed an unsuccessful application for habeas corpus relief under 28 U.S.C. § 2255 followed by an equally unsuccessful appeal. United States v. Glinsey, 57 Fed.Appx. 211 (5th Cir. 2003).

Several years later, Glinsey sought a writ of coram nobis from the district court challenging his conviction and contending that (1) an incriminating tape (relevant only to the witness tampering charge) was wrongfully obtained and used; (2) the government failed, under 18 U.S.C. § 3504, to admit or deny that the tape recording was obtained unlawfully; (3) deficiencies exist *915 ed in the information used to charge him; and (4) he received no hearing on his various challenges to his conviction and sentence. 2 The district court denied relief.

Glinsey contends that, as a result of his convictions, he now suffers from various civil disabilities such as not being able to run for public office. We need not address whether the civil disabilities Glinsey alleges qualify for coram nobis relief because we conclude that the district court correctly determined that Glinsey failed to meet the high burden of proving entitlement to such relief. Glinsey’s claims either already have been raised, should have been raised previously, or are not errors “of the most fundamental character” as necessary to support a request for coram nobis relief. United States v. Dyer, 136 F.3d 417, 422 (5th Cir. 1998).

As such, for substantially the same reasons expressed in the district court’s opinion, the judgment of the district court is AFFIRMED.
