Graduating seniors at Dunbar Senior High School are slated to receive words of wisdom from none other than the Rev. Al Sharpton at their commencement ceremony on Wednesday.

Sharpton is scheduled to deliver the keynote speech at the 10 a.m. ceremony at Howard University’s Crampton Auditorium. It’s his second speech associated with Dunbar in the last two years: In August 2010, Sharpton organized speakers on Dunbar’s football field to commemorate the 47th anniversary of Martin Luther King Jr.’s “I Have A Dream” speech and counter a Tea Party rally held on the National Mall.
