Both candidates are on the attack again with just over a week left in their contentious and closely watched race.
Democrat Alison Lundergan Grimes' campaign challenged a new ad from Republican Senator Mitch McConnell that boasted his support among women. The Grimes campaign says it features a woman who is registered to vote in Pennsylvania.
The McConnell camp says she's a college student at the University of Louisville who hasn't updated her voter registration yet.
In a separate spat, the McConnell campaign said a new ad falsely accused him of using his office to improve his personal investments during the 2008 financial crisis.
