A Cruz ad said Trump thinks "a grown man pretending to be a woman (should) be allowed to use the women's restroom."

There's a grain of truth in this claim, but the overall message is highly distorted to scare voters.

Trump did say he'd be fine with letting Caitlyn Jenner, a transgender women, use the bathroom of her choice in Trump Tower rather than the bathroom that corresponds to the sex on Jenner's birth certificate. But Trump did not say he supports a man "pretending to be a woman" using a woman's restroom.

Trump talked about how bathroom laws that allow people to use the bathroom of their choice are not a problem and bemoaned the business backlash that hit North Carolina with a state law that said people have to use the bathroom that corresponds with their gender at birth. The state would have been better off leaving it alone, he argued, but as president he would not want the federal government to be involved.

Doing nothing about a local government's decision is not an endorsement. We rate Cruz’s claim Mostly False.
