Charlton Ray McDonald pleaded guilty to the possession of child pornography and was sentenced to 120 months of imprisonment and three years of supervised release.

He argues on appeal that the district court erred in denying his motion to withdraw his guilty plea. He contends that he was entitled to have his plea withdrawn because his counsel was ineffective for failing to investigate or advise him concerning the defense of necessity before advising him to plead guilty.

When determining whether to allow a defendant to withdraw his guilty plea, the district court should consider whether: (1) the defendant has asserted his innocence, (2) withdrawal would prejudice the Government, (3) the defendant has delayed in filing his withdrawal motion, (4) withdrawal would substantially inconvenience the court, (5) close assistance of counsel was available, (6) the original plea was knowing and voluntary, and (7) withdrawal would waste judicial resources. United States v. Carr, 740 F.2d 339, 343-44 (5th Cir. 1984). *415 McDonald has not shown that the district court abused its discretion in determining that he was not entitled under the Cmr factors to have his guilty plea withdrawn. See United States v. Powell, 354 F.3d 362, 370 (5th Cir. 2003); Carr, 740 F.2d at 343-44.

AFFIRMED.
