Barbara Walters just told President Barack Obama she's retiring next year ... this according to a source who heard Barbara say it.
Barbara just finished interviewing the Prez at the White House. According to the source, during a break in the action, Barbara leaned over to Obama and said, "I need one more interview with you because I'm retiring next year." Here's the thing .. Barbara's mic was open when she said it, and lots of people were listening.
Barbara still does specials for the network, in addition to "The View." Her "Most Fascinating People" show aired last night -- Obama was NOT on her list.
We called ABC News for comment, but so far ... nothing.
