LINCOLN, Neb. (AP) – The Nebraska Democratic Party alleges in a complaint that Republican U.S. Senate candidate Jon Bruning failed to disclose his ownership interest in a $675,000 vacation home. Party officials filed the complaint Monday. The complaint alleges that Bruning, the state attorney general, failed to disclose the shared home near Ashland in his 2008, 2009 and 2010 financial interest statements.  One provision cited in the complaint includes an exception for real estate owned by businesses. Bruning and two businessmen bought the home through a limited liability corporation, which was disclosed in another part of the forms. Democratic officials say that isn’t enough to comply. Bruning campaign manager Trent Fellers said Democratic officials are trying to divert attention from U.S. Sen. Ben Nelson’s support of the controversial federal health care law.
