Former President Barack Obama said Tuesday on “CBS Mornings” that the “divided media” was his biggest concern for the future of the United States.

Host Nate Burelson asked, “Post-presidency, what about this country keeps you up at night?”

Obama said, “The thing that I’m most worried about is the degree to which we’ve now had a divided conversation, in part because we have a divided media.”

He continued, “When I was coming up, you had three TV stations. And people were getting a similar sense of what is true and what isn’t, what was real and what was not. Today, what I’m most concerned about is the fact that because of the splintering of the media, we almost occupy different realities.”
