NEW HAVEN, Conn. (AP) A federal judge has delayed the sentencing of former Connecticut Gov. John Rowland in a campaign fraud case because of defense lawyers' concerns about some evidence.

U.S. District Judge Janet Bond Arterton in New Haven on Monday postponed Rowland's sentencing, which was scheduled for Wednesday. A new sentencing date wasn't immediately released.

Rowland was convicted in September of conspiring to hide payments for work he did on the failed 2012 5th congressional district campaign of Lisa Wilson-Foley, through a phony contract with a nursing home business owned by her husband, Brian Foley.

Rowland's lawyer, Reid Weingarten, asked for the delay, telling Arterton he didn't know that Brian Foley told his wife that a law firm signed off on the deal with Rowland.

Rowland potentially faces more than three years in prison.
