Tennessee lawmakers have approved a controversial bill that would allow mental health therapists and counselors to turn away LGBT patients.

The Republican-controlled Senate voted 25-6 in favor of the measure on Monday, following passage last week in the GOP-led House.

Republican Governor Bill Haslam has not said whether he will sign the bill into law. Once it reaches his desk, he has 10 day to decide.

The bill states that counselors can refuse to treat clients based on their “sincerely held principles,” a change from the bill's original language of “sincerely held religious belief.”

Opponents say the measure could negatively impact young LGBT people.

Tennessee lawmakers are also considering legislation that would outlaw transgender people from accessing the bathroom that matches the gender they identify with.
