Larry Craig is appealing his sex sting conviction.
WASHINGTON (CNN) - Lawyers for Sen. Larry Craig asked a Minnesota appeals court Tuesday to allow him to withdraw his guilty plea stemming from his June arrest in a public bathroom sex sting, citing a "grave procedural flaw."
The Idaho Republican argues that a state law related to his misdemeanor conviction is unconstitutional and that it "manifestly unjust" not to allow the lawmaker to be given another chance to prove his innocence.
