LAWRENCE, Kan. (AP) -- Former Secretary of Defense Donald Rumsfeld will speak July 26 at a forum on current affairs at the Dole Institute of Politics in Lawrence.

Rumsfeld served as secretary of defense from 1975 to 1977 and again from 2001 to 2006, working for two Republican administrations after the Vietnam War and through the wars in Iraq and Afghanistan. He also was a four-term congressman from Illinois from 1962 to 1969.

Bill Lacy, director of the Dole Institute, said Rumsfeld's appearance will give insight into U.S. history and how policy was made by different administrations.

Rumsfeld will also be signing copies of his memoir for the public.
