TRENTON -- A national television ad advocating for tolerance of transgender people is scheduled to air on Fox News Channel the same night the Republican nominee Donald Trump accepts his party's nomination.

A coalition of LGBT groups called Fairness USA announced it will air a 60-second spot on July 21, the final evening of the convention, depicting a transgender woman being denied access to a women's bathroom at a restaurant.

Backed by the Movement Advancement Project, it will air on both Fox News the evening of Trump's speech, and will air subsequently airing on Fox Business Network.

In March, North Carolina's governor signed into law a bill blocking cities from allowing transgender individuals to use public bathrooms for the sex they identify with.

In the ad, a transgender woman narrates her own story, saying that "in most states, our laws don't prevent transgender people from discrimination in public places."

As she is shown walking across restaurant dining room to use the ladies restroom, she is blocked from entering by a restaurant employee. Several men are seen scowling and sneering at her from inside of the men's room which she is informed she must use instead.

On Monday, Republican convention delegates meeting in Cleveland ahead of next week's nominating convention adopted strident language opposing the Obama administration's policy on transgender bathrooms for school children in a platform subcommittee hearing.

The RNC draft platform says the Obama adminitration's guidance is "illegal and dangerous" and "alien to America's history and traditions."

Trump, however, has maintained that transgender people should be able to use whatever bathroom they want.
