Marking 50 years since 'I Have a Dream'

WASHINGTON - President Barack Obama will join former Presidents Jimmy Carter and Bill Clinton at the Lincoln Memorial Wednesday to mark the 50th anniversary of the March on Washington for Jobs and Freedom.

Obama says he considers the 1963 march and the Martin Luther King Jr. "I Have a Dream" speech a "seminal event."

He says the anniversary is a good time to reflect on how far the country has come and still has to go.
