WASHINGTON - Power outages left many wondering who turned out the lights in D.C. on Tuesday-- including OprahWinfrey. The power went off at D.C.'s Warner Theatre, right in the middle of Ms. Winfrey's speech honoring Maya Angelou. Winfrey was part of the dedication ceremony of a new U.S. Postal Service Forever Stamp that honors Angelou. "I am honored to be here to stand her as her daughter, sister-friend at the unveiling of the Maya Forever-- FOREVER-- stamp," Winfrey said, and then the lights went out.
