The U.S. House of Representatives has just voted to bar Planned Parenthood health centers from all federal funding for birth control, cancer screenings, HIV testing, and other lifesaving care.

It is the most dangerous legislative assault in our history, and it cannot go unanswered. Planned Parenthood and the three million women, men, and teens who are at risk of losing access to basic care — need you to stand united now.

Sign the open letter to every single representative in the House who voted for this cruel, unconscionable, unthinkable law, and to every senator who still has a chance to stop it.

Please join me in standing with Planned Parenthood by reading and then signing this letter.
