Following Donald Trump’s (now reversed) comments in opposition to North Carolina’s anti-LGBT law, the presidential campaign for his rival Sen. Ted Cruz (R-Texas) has issued an ad stoking fears about transgender people using the restroom.

The 27-second black-and-white ad, published on Thursday, displays of series of photos of public restrooms as well as a shot of a woman holding hands with a young girl. As images of Trump are shown, a sound clip is played of him saying transgender people should “use the bathroom they feel is appropriate.”

“Should a grown man pretending to be a woman be allowed to use the women’s restroom?” the ad says. “The same restroom used by your daughter? Your wife? Donald Trump thinks so. It’s not appropriate. It’s not safe. It’s P.C. nonsense that’s destroying America. Donald Trump won’t take on the P.C. police.”

The ad is similar to one that aired in Houston late last year ahead of a ballot vote on an LGBT-inclusive non-discrimination ordinance that equated transgender people to sexual predators entering restrooms for nefarious purposes. The widely discredited notion non-discrimination laws would endanger women and children in public restrooms is credited with the defeat of the ordinance at the ballot box.

The Cruz ad follows up on the candidate’s criticism of Trump for opposing the North Carolina’s anti-LGBT law, which prohibits transgender people from using public restrooms consistent with their gender identity. Trump has since backtracked on his opposition to the law and said “local communities and states should make the decision” on transgender bathroom use.

Jay Brown, a spokesperson for the Human Rights Campaign, said the Cruz ad amounts to attack on transgender Americans, who instead of vulnerable predators are a vulnerable segment of the American population.

“Ted Cruz’s transphobic smear campaign peddles a dangerous brand of hate and ignorance,” Brown said. “At a time when transgender women are at a disproportionately high risk for violence and assault, Ted Cruz’s reckless ad puts them at even greater risk. Moreover, what message does Ted Cruz think this sends to transgender youth across this country? We deserve a president who’ll fight to protect the rights and dignity of everyone — not a reckless, feckless politician who’ll do or say anything to score a point.”
