The re-election campaign for Sen. Richard Lugar, R-Ind., announced Wednesday that former U.S. Secretary of State Condoleezza Rice will attend a fundraising reception for Lugar in Indianapols this weekend.
Rice said in a statement that Lugar "has proven his ability to be a positive force for our American principles and for our party. As such, I am proud to support his bid for re-election."
Lugar is being challenged in the May 8 Republican primary election by state Treasurer Richard Mourdock.
Rice was national security adviser and secretary of the State Department under President George W. Bush, and worked closely with Lugar, who has chaired or been the ranking Republican on the Foreign Relations Committee, his campaign said.
The Lugar campaign did not say when or where the fundraising reception will be.
