The 69-year-old former state treasurer was convicted on 14 counts of bribery and extortion last week.
Shoffner's attorneys are asking a federal judge to acquit her because the government "failed to present sufficient proof on each and every element."
In a three-page motion, attorney Grant Ballard says a jury should not have found Shoffner guilty under the Hobbs Act or the federal bribery statute.
The Hobbs Act deals with affects on interstate commerce. Attorneys argue the there is no federal interest in the alleged crimes to warrant prosecution under the bribery statute.
"The government failed to produce any such evidence making a Judgement of Acquittal necessary," the pleading reads.
Shoffner resigned from the state treasurer's office in May 2013 after her arrest by federal agents at her home in Jackson County for accepting money in exchange for steering state business to a bond broker.
Shoffner is set to stand trial next month on additional charges related to misuse of campaign funds.
