John Glenn, the former astronaut who became the first American to orbit the Earth, has died at the age of 95, Ohio State University has confirmed.

Glenn later spent 24 years representing Ohio in the U.S. Senate and also became the oldest person in space in 1998.

Fox News Sunday anchor Chris Wallace joined Shepard Smith Thursday afternoon as the news broke to remember the American hero.

"He was the exemplar of 'the right stuff' and became an instant national hero," said Wallace.

Wallace covered Glenn during the latter's time as a senator, but there was always something a bit different about him.

"This wasn't a senator," Wallace said. "This was John Glenn, an American hero, and so you felt a genuine sense of thrill and honor to be in his presence."

"He was a genuine American hero," Wallace said. "We use that word hero too often. He really was."
