"Because that was where it all started for me, I wanted this to be the place, and I wanted you all to be the first to know that this summer I'm going to retire," he said. "It's been a great adventure. You know, I'm one of the luckiest people in the world because as a little boy, as a young reporter, I always wanted to be a journalist, and I got to do that. And not many people get to do that, and I couldn't have asked for a better life or something that was more fun and more fulfilling."
He later confirmed the news on Twitter.
"Great talking journalism at @TCU tonight. Also really happy to be in my hometown, where it all started, to announce my retirement," he wrote.
The 78-year-old has been with CBS News for the past 46 years, spending the past 24 as anchor of its Sunday morning news program, Face the Nation.
