On Wednesday, over 550 celebrities relaunched a group first organized during the post-World War II Red Scare: the Committee for the First Amendment. Their intent is to stand up in what they call a “defense of our constitutional rights,” adding: “The federal government is once again engaged in a coordinated campaign to silence critics in the government, the media, the judiciary, academia, and the entertainment industry.”

The current group is headlined by actor and activist Jane Fonda — whose father, actor Henry Fonda, was one of the early members of the first Committee for the First Amendment, which was founded in the 1940s to oppose the infamous House Un-American Activities Committee, through which the federal government accused many top entertainers of being communists or communist sympathizers and derailed their careers.

Other members of the newly re-formed committee include filmmakers Spike Lee, Barry Jenkins, J.J. Abrams, Patty Jenkins, Aaron Sorkin and Judd Apatow; TV show creator Quinta Brunson; musicians Barbra Streisand, John Legend, Janelle Monáe and Billie Eilish; comedians Tiffany Haddish and Nikki Glaser; as well as actors Mark Ruffalo, Anne Hathaway, Kerry Washington, Pedro Pascal, Natalie Portman, Viola Davis and Ben Stiller. Another signatory is actor Fran Drescher, who last month ended a term as the president of the SAG-AFTRA union, whose membership includes NPR’s journalists.

In the letter, the authors write: “This Committee was initially created during the McCarthy Era, a dark time when the federal government repressed and persecuted American citizens for their political beliefs. They targeted elected officials, government employees, academics, and artists. They were blacklisted, harassed, silenced, and even imprisoned. The McCarthy Era ended when Americans from across the political spectrum finally came together and stood up for the principles in the Constitution against the forces of repression.”

“Those forces have returned. And it is our turn to stand together in defense of our constitutional rights,” the letter continues. The group says that defending free speech and free expression is not a partisan issue.

In a letter inviting her peers to join the re-established group, Fonda writes: “I’m 87 years old. I’ve seen war, repression, protest, and backlash. I’ve been celebrated, and I’ve been branded an enemy of the state. But I can tell you this: this is the most frightening moment of my life. When I feel scared, I look to history. I wish there were a secret playbook with all the answers — but there never has been. The only thing that has ever worked — time and time again — is solidarity: binding together, finding bravery in numbers too big to ignore, and standing up for one another.”
