FRANKFORT, Ky. (AP) -- The candidates in Kentucky's U.S. Senate race are answering questions together for the first time amid a squabble over a bus rental.
Republican Sen. Mitch McConnell is accusing Democrat Alison Lundergan Grimes of accepting potentially illegal campaign gifts from her father's bus company.
The Grimes campaign says it sampled rates from four companies before deciding how much to pay to rent an 11-year-old luxury bus from Jerry Lundergan's company. The campaign calls McConnell's criticism a "hit job."
Four rental companies say Grimes' rate is accurate, but one company says it would have charged more because it would have required a fee every day regardless of whether the bus was used.
Grimes and McConnell are scheduled to meet Wednesday in Louisville at a forum sponsored by the Kentucky Farm Bureau.
