ABC News' Yunji de Nies reports: Michelle Obama has a special message this Father's Day: "celebrate responsible fatherhood and the men who've had the courage to step up." In a statement, the First Lady declares this 100th anniversary of Father's Day, "not just any day." She praised her own late-father as "our provider, our champion and our hero" and says the example Frasier Robinson, "the rock" of her family, laid out, "continues to guide me every day." She writes that while her husband, "didn't have my good fortune — his father left when he was just two years old…he has always been determined to give our daughters what he never had, and he values being a good father more than any other accomplishment in his life." Mrs. Obama included a videolink to her husband's Father's Day celebration that took place Friday at the White House. She urges Americans to celebrate "the men who've had the courage to step up, be there for our families, and provide our children with the guidance, love and support they need to fulfill their dreams."
