Following the passage of a controversial law in North Carolina that, among other things, prevents transgender people from using public bathrooms that do not match the gender on their birth certificates and rolls back local anti-discrimination measures for LGBTQ people, Mayor Muriel Bowser signed an order banning D.C. government employee travel to the Tarheel State.

“We stand w/ the LGBTQ community & against discrimination,” she wrote in a tweet.

The order (which you can read in its entirety below) prohibits travel to “ensure a constant voice in policy and practice in the District of Columbia in favor of equal treatment for members of the LGBTQ communities” until the law in question is “permanently enjoined, repealed, or amended.” It is effective immediately.

Bowser similarly issued an order banning city employees from traveling to Indiana after the state passed the Religious Freedom Restoration Act a year ago. She rescinded the order a week later, saying that the state removed the discriminatory language from the bill.

D.C. joins Connecticut, New York, Vermont, Boston, San Francisco, and others, which have also implemented travel bans to North Carolina over the law.
