Former U.S. Sen. Richard Lugar will make his first public speech since leaving office when he appears Feb. 12 at Duke University's Sanford School of Public Policy in Durham, N.C.

The Republican from Indianapolis will speak about the country's divisive political climate, according to his spokesman. His speech can be viewed online at www.ustream.tv/Duke-University.

Lugar left the Senate on Jan. 3 after a 36-year career on Capitol Hill. He lost last year's Republican primary election to State Treasurer Richard Mourdock, who was defeated in the general election by then-Rep. Joe Donnelly, D-2nd.
