Students at Kansas State University got a hands-on lesson in foreign policy from a very important guest.

CIA director Michael Hayden spoke to a group of students this afternoon as part of the London Lecture Series.

Hayden spoke on topics ranging from to trade to china and called on Americans to learn foreign languages to meet new challenges.

Hayden also predicted more tension between the United States and Europe because of different views on terrorism.

But, Hayden wasn't the only special visitor in the sunflower state today. Over in Lawrence Supreme Court Chief Justice John Roberts gave a lecture to students on The University of Kansas campus.
