Former Arkansas treasurer Martha Shoffner is asking a federal judge to throw out corruption charges on which she is to be tried in a little over a week.
Shoffner faces trial March 3 on a 14-count extortion and bribery indictment, which accuses her of accepting $36,000 from a bond dealer in exchange for steering state business his way.
Shoffner asked Friday that the counts be thrown out on grounds that the allegations don't involve interstate commerce. Lawyers for Shoffner argue that to allow prosecution would "extend federal power beyond its proper bounds."
Shoffner faces another 10 counts of mail fraud for allegedly misspending $9,800 in campaign money, on which she is to be tried separately.
Shoffner was in her second term as treasurer last year when she was arrested.
