From The Huffington Post: Barack and Michelle Obama will appear on Oprah Winfrey's show on April 27, it was announced Tuesday.
Obama will be in Chicago for a series of fundraisers and will sit down for a taped interview. The interview will air on May 2, and will presumably be the final interview Oprah has with the pair on her talk show, which is ending on May 25.
Oprah, of course, is a longtime backer of the Obamas, and has interviewed the two numerous times before. Most recently, she interviewed Michelle Obama in January, where the two discussed military families.
