It should come as no surprise that the ACLU has a long history of collaborating with the entertainment history. After all, freedom of expression is one of our cornerstone issues, so it makes sense that those who work in film, television, music and other related fields would appreciate the ACLU’s long history of defending free speech and fighting censorship.

Lately, we’ve been reaching out to partner with influential creative artists on a whole range of civil liberties issues, such as voting rights, privacy and security, overincarceration, racial justice, reproductive rights, and more. Our collection of celebrity supporters even has an official name: the ACLU Ambassador Project.

Our newest ambassador is Michael Kenneth Williams, best known for his remarkable work on The Wire, which ran for five seasons on HBO. Each ambassador has a particular cause they’ll be advocating for, and Williams will be working with us to end mass incarceration. Other celebrities taking part include Lewis Black (voting rights), Melissa Etheridge (marijuana reform), Harry Belafonte (overincarceration of juveniles), and Cyndi Lauper (LGBT rights). Check out our full roster of ambassadors here.

Each ambassador will be helping us out in a different way, so if you keep your eyes peeled you’re likely to see one of them participating in a news conference, meeting with members of Congress, attending a legislative hearing, or maybe just using their social media accounts to spread messaging about their particular issue. Just as a movie or a song can bring attention to an important issue, so too can familiar faces who are willing to speak out. We’re happy to have a team of impassioned ambassadors, and we hope you’ll join us in welcoming them to the ACLU family.
