Michael Moore, Kerry Washington, Rosie O’Donnell, Harry Belafonte, Jane Fonda, Dylan McDermott, Roseann Barr, and Lily Tomlin are among the film and television stars who have pledged to “speak out in every way possible” to prevent Trump from becoming the next President of the United States as part of the new “Stop Hate Dump Trump” campaign.

In a statement on its website, the group says it believes Trump is “a grave threat to democracy, freedom, human rights, equality, and the welfare of our country and all our people.”

“We have witnessed Trump inciting hatred against Muslims, immigrants, women, the disabled,” the campaign’s website reads. “We have seen him evidencing dangerous tendencies that threaten the bedrock of democracy: unleashing a lynch mob mentality against protesters, calling for the expulsion of Muslims from the country, bullying, and fear-mongering.”

“History has shown us what happens when people refuse to stand against hate-filled leaders,” statement continues. “We pledge ourselves to speak out in every way possible against the politics of hate and exclusion he represents.”

Other notable signatories on the campaign include Noam Chomsky, Connie Britton, Rosanna Arquette, Reza Aslan, Ani DiFranco, Danny Glover, and playwright Eve Ensler.

“We are offering Americans a chance to be heard and engage in action, as Trump’s campaign gains momentum even as he increases his hateful and divisive rhetoric,” Ensler said in a statement.
