Martha Raddatz isn't done with Centre College yet.

Raddatz, the ABC News senior foreign affairs correspondent, hosted the 2012 vice presidential debate at Centre last month. On Friday, the private liberal arts school in Danville said Raddatz will return May 19 as the featured speaker at Centre's 190th commencement ceremony.

Raddatz has covered stories for ABC News — and before that, for National Public Radio — all over the world, including the U.S. wars in Iraq and Afghanistan. She is the author of The Long Road Home: A Story of War and Family, a look at how the stateside families of the 1st Cavalry Division coped during the Iraq War.
