Presumptive Republican presidential nominee Donald Trump recently spoke with Caitlyn Jenner ahead of what is likely to be a contentious debate over transgender issues in the party’s platform.

The call between the former Olympic decathlete and the billionaire came days after Trump met with hundreds of religious conservatives, according to The New York Times.

Delegates on Monday are expected to debate whether to adopt a provision defending laws that prevent transgender men and women from using the public restroom of their choice.

About half of all states are suing the Obama administration’s directive to protect transgender students.
