Florida ? U.S. Rep. Katherine Harris said Thursday she did not knowingly do anything wrong in her associations with a defense contractor who prosecutors say illegally funneled thousands of dollars to her campaign in 2004.

Questions about the donations have arisen as Harris, the former Florida secretary of state who oversaw the 2000 presidential election recount, tries to unseat U.S. Sen. Bill Nelson, D-Fla.

The donations were described in a plea agreement a week ago, when Mitchell Wade, the former president of MZM Inc., pleaded guilty to bribing U.S. Rep. Randy “Duke” Cunningham in exchange for assistance in getting $150 million in Defense Department contracts for his company.

He also admitted making illegal campaign contributions in the names of MZM employees and their spouses to Harris and Rep. Virgil Goode, R-Va. Prosecutors said Harris received $32,000 from employees who were reimbursed by Wade. Harris said she recently donated the money to charity.

In the plea agreement, Wade acknowledged meeting with Harris in 2005 to discuss a possible fundraiser for her and obtaining funding for a Navy counterintelligence program involving his company.
