President Barack Obama on Monday announced plans to issue an executive order protecting transgender federal employees from workplace discrimination.

According to the Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, the president announced the upcoming order at the White House's annual reception marking LGBT Pride Month.

“I've asked my staff to prepare a second executive order so that federal employees – who are already protected on the basis of sexual orientation – will now formally be protected from discrimination based on gender identity as well,” Obama said during the East Room celebration.

“The majority of Fortune 500 companies already have nondiscrimination policies to protect their employees because it's the right thing to do and because many say it helps to retain and attract the best talent. And I agree. So if Congress won't act, I will.”

Earlier this month, Obama announced he would sign an executive order prohibiting federal contractors from discriminating on the basis of sexual orientation or gender identity.

“We've got a lot to be proud of, but obviously we can't grow complacent,” Obama said. “We've got to defend the progress that we've made.”
