Celebrities on the red carpet at Sunday's Oscars pre-show are sporting little blue ribbons in the lapel area as a silent political statement in support of the American Civil Liberties Union.
The ACLU is a national organization that defends and supports, according to their website, "our nation’s...liberty, [by] working in courts, legislatures, and communities to defend and preserve the individual rights and liberties that the Constitution and the laws of the United States guarantee everyone in this country."
They are known for taking up LGBT causes but they have expanded their mission lately to include, "establishing new privacy protections for our digital age of widespread government surveillance, ending mass incarceration, or preserving the right to vote or the right to have an abortion, the ACLU takes up the toughest civil liberties cases and issues to defend all people from government abuse and overreach."
Their website landing page has a gigantic picture of President Donald Trump in the carousel with the description, "He discriminated: We sued." The picture links to an outline of the lawsuit they filed against Trump's temporary travel ban barring travel from seven Muslim-majority countries. That lawsuit resulted in a temporary stay of the order and forced the Trump administration to draft another version, to be released the first week of March.
