The Nevada State Democratic Party filed a complaint with the Federal Election Commission Tuesday against Republican Senate candidate Sue Lowden for accepting an RV as an in-kind donation.

The Lowden camp said it's leasing the 2001 Monaco Executive Motorhome from supporter Carl Giudici, but the Democrats say the arrangement violates election law.

"The 'lease' with Mr. Giudici is irrelevant and, frankly, pointless," Bradley Schrager, an attorney for the Nevada Democrats, said in a statement. "She is 'leasing' a vehicle she already owns. The lease language does not in any way affect Nevada's determination of who owns this vehicle — Sue Lowden."

The Lowden camp said there's nothing wrong with the arrangement for its use of the "nearly decade-old RV."

"The Sue Lowden for U.S. Senate campaign has rightfully entered into a private lease agreement, with a private owner of this RV, to compensate the owner for the fair market value for the RV's use," Robert Uithoven, Lowden's campaign manager, said in a statement. "The payments and in-kind contributions have been fully and properly disclosed to the FEC. In addition, the lease agreement clearly states that Sue Lowden and the Sue Lowden for U.S. Senate campaign is not, has never been nor ever will be the owner of this private individual's RV.

"The campaign will continue to provide full compensation for the operation, use, maintenance, fuel and insurance on this RV, and we will continue to report such expenses as required by law."

The campaign provided a copy of the lease agreement to the Ballot Box but it did not specify how much it's paying for the vehicle's use.
