The secretary of the U.S. Department of Homeland Security, Jeh Johnson, will deliver a Landon Lecture on May 27 at Kansas State University.

Before becoming the fourth secretary of homeland security, Johnson was general counsel of the Department of Defense. He also has extensive service in national security, law enforcement and as a private attorney.

Kansas State spokesman Jackie Hartman noted in a news release that Johnson is visiting Manhattan as it prepares for construction of the National Bio and Agro-Defense Facility to begin next to the Kansas State campus this summer. The animal disease research laboratory will be part of the Department of Homeland Security.
