Politicians, civil rights leaders, entertainers and elected officials will commemorate the 50th anniversary of Dr. Martin Luther King's historic "I Have a Dream" speech Wednesday.
Though the exact schedule for the "Let Freedom Ring and Call to Action" commemoration still has not been publicly released, the events are expected to begin at about 11 a.m.
A speech by President Obama will be last, expected to begin at about 2:45 p.m., before bells ring out at 3 p.m. to mark the moment King ended his speech 50 years ago.
Other noteable speakers who have been announced include former Presidents Jimmy Carter and Bill Clinton. Also expected to speak are Rep. John Lewis, the last surviving member of the original "Big Six" civil rights leaders who staged the 1963 march; Ambassador Andrew Young and the Rev. Al Sharpton.
Oprah Winfrey is expected to speak, as is Oscar and Grammy Award winner Jamie Foxx.
Gospel singer BeBe Winans, with brothers Marvin and Carvin, is expected to perform, as is LeAnn Rimes, contemporary Christian signer Natalie Grant, and folk singers Peter Yarrow and Paul Stookey, whose group Peter, Paul and Mary performed at the 1963 march.
Emcees for the event are Soledad O'Brien and Hill Harper.
