"I Have a Dream" - four words that helped change the course of American history. ABC News and Yahoo! News will host a first-ever live global broadcast on Wednesday, August 28 to commemorate the 50th anniversary of Martin Luther King's March on Washington and his iconic "I Have a Dream" speech. This hybrid digital-television event will be anchored by George Stephanopoulos along with Dan Kloeffler from ABC News World Headquarters in New York beginning at 11:00 a.m., ET.
Coverage will be available across all ABC News Digital platforms as well as through Yahoo! News. When President Obama speaks from the steps of the Lincoln Memorial ABC News will simulcast a live special report to the ABC Television Network and to the Yahoo!-ABC News Network.
ABC News will have a team of correspondents, anchors, and guests contributing to its anniversary coverage throughout the day:
Special coverage will also air on all broadcasts throughout the day including " Good Morning America" (7:00 a.m., ET) " World News with Diane Sawyer" (6:30 p.m., ET) and " Nightline" (12:35 a.m., ET). 50 years ago, two 10th grade African-American girls rode a bus from Little Rock, Arkansas to Washington DC for the March on Washington. Little Rock had been seared by integration efforts and 15-year-old Sarah Davidson and 16-year-old Diana Watson Ezell had gotten involved with their local NAACP. They've revisited their stops this past weekend and will return to DC for the anniversary of the March. Byron Pitts visits with them to reflect on what happened 50 years ago and where we stand as a nation today for a special report airing on "Nightline."
