The Nebraska Democratic Party has filed an ethics complaint with the state against Republican U.S. Senate candidate Deb Fischer, accusing her of not disclosing a conflict over a piece of land that was later involved in a bill she introduced.

Fischer and her husband unsuccessfully sued their neighbors in 1995 claiming ownership of a disputed parcel of land along the Snake River.

In its complaint filed Tuesday with the Nebraska Accountability and Disclosure Commission, the Democratic Party says that a bill by Fischer in 2011 hampered the sale of that land to the Nebraska Game and Parks Commission.

Fischer's campaign has called the conflict charge "outrageous," noting that her legal conflict over the land was long over by the time the bill was introduced.
