From a People for the American Way press release:

The Hip Hop Caucus heads to Capitol Hill Tuesday to speak out for the filibuster – joining members of the Congressional Black Caucus and People For the American Way.
The Hip Hop Caucus is organizing youth leaders to ensure that young people understand the stakes for their generation in the battle over the filibuster and judicial nominations. Plans for a large-scale, long-term effort to involve students and amplify their voice will be announced at the press conference.
With the showdown counting down next week, the hip hop generation and civil rights veterans are coming together to find common cause – detailing the importance of the filibuster and the federal judiciary in protecting hard-won social justice victories, and making greater progress in the future.
