Students on UT's campus were treated to a speech from a former senior U.S. senator on Tuesday.

Richard Lugar was Indiana's longest-serving senator. He was in office from 1977 until earlier this year.

The Republican spoke about international affairs and the need for international education. His talk touched on subjects like the conflicts in Syria and Egypt among other things.

Senator Lugar was known for his work on global security, and it's a subject he hopes the students take seriously.

"It's a great opportunity for students right now in a world that really begs for this kind of concentration," he said.

One of Lugar's best known accomplishments was the Nunn-Lugar Act. It led to the dismantling of thousands of nuclear weapons across the former Soviet Union states.

Earlier this month, the White House announced president Obama plans to give Lugar the Presidential Medal of Freedom, the highest civilian honor.
