John Glenn says facts about scientific discovery should be taught in schools — and that includes evolution.

The 93-year-old former astronaut and U.S. senator tells The Associated Press in an interview that he sees no contradiction between believing in God and believing in evolution. When he went back into space in 1998, he had announced that "to look out at this kind of creation out here and not believe in God is to me impossible."

The Democrat also says he doesn't plan to stump for or endorse any candidates in 2016. He has weathered a year of health difficulties, including a small stroke, and has lost half his vision and some hearing.

He and his wife, 95-year-old Annie, say they'll devote their energies to ramping up the John Glenn College of Public Affairs at Ohio State University.
