Instead of being in Washington on Wednesday, Senate Majority Leader Harry Reid (D-Nev. planned to take part in a commemorative event in Nevada and call into a black radio station in Las Vegas, aides said.)

Dozens of activists, actors, boldface names, former presidents and members of the family of the Rev. Martin Luther King Jr. are speaking at events to mark the 50th anniversary of the March on Washington.

But not one leader of the House or Senate is in attendance, on stage or speaking at the event.

Other lawmakers spoke at the official commemoration in Washington on Wednesday, including Rep. John Lewis (D-Ga.) -- the only surviving speaker from the 1963 march -- and Reps. Joaquin Castro (D-Tex.) and Donna Edwards (D-Md.). Sen. Angus I. King (I-Maine) also spoke, but no Republican lawmakers delivered remarks.
