Texas state lawmakers spent the night hearing arguments for and against the bill known as the "Texas Privacy Act."
Hundreds signed up to testify on the so-called "bathroom bill." The measure would ban cities from adopting non-discrimination ordinances that would apply to restrooms, and nullify existing local laws.
Austin, Dallas, and San Antonio, currently have ordinances that would be overturned under HB 2899.
"I do believe it's important for privacy protection," said Rep. Ron Simmons (R-Carrollton). "I think there are some protection issues, and I've heard from my constituents concerned about what the unintended consequences might be about opening up restrooms."
"They're putting her life at risk on a daily basis by suggesting we pass this legislation," said Rachel Gonzales, the mother of a transgender girl. "HB 2899 would remove my daughter's school's ability to keep her safe."
Governor Greg Abbott recently voiced his support for the bill, after months of silence on the issue.
