Former Connecticut Gov. John Rowland has asked a federal appeals court to overturn his political corruption conviction.
The Republican wouldn't comment on Friday as he left oral arguments before the 2nd U.S. Circuit Court of Appeals in New York City.
Rowland was sentenced to a two-year prison term last year after being convicted on a charge of conspiring to disguise work he did on a failed 2012 congressional campaign. He is free on bail.
His attorney, Andrew Fish, has claimed the government withheld evidence that would have benefited the defense and has misapplied a federal law.
Prosecutors have denied those charges and argued the conviction should stand.
Rowland resigned from office in 2004 amid a corruption scandal and served 10 months in prison for taking illegal gifts
