President Donald Trump on Wednesday withdrew guidelines issued to public schools in defense of transgender student rights.

The guidance, set by former President Barack Obama in May 2016, let students choose which restroom to use based on their chosen gender identity.

Celebrities including Jazz Jennings and Laverne Cox, who identify as transgender, took to Twitter early Wednesday to share their support for the Obama-era guidelines.

After the Trump administration’s announcement, many others shared their concerns.
