Celebrities are donning the ribbon in support of the American Civil Liberties Union (ACLU), an organization that challenged President Donald Trump’s controversial travel ban in court.

“I’m wearing an ACLU ribbon because they’re fighting incredible fights right now for American ideals,” Lin-Manuel Miranda said.

The organization has received unprecedented support since Trump’s inauguration, raising $24.1 million over one weekend to fight the travel ban. The ACLU also fights for LGBTQ rights, First Amendment rights, government transparency, immigrant rights, and woman’s rights, among other issues.
