The Republican-controlled House and Senate voted to override GOP Gov. Asa Hutchinson’s veto of the measure, which prohibits doctors from providing so-called gender confirming hormone treatment, puberty blockers or surgery to anyone under 18 years old, or from referring them to other providers for the treatment.

Opponents of the measure have vowed to sue to block the ban before it takes effect this summer.

Hutchinson said the measure went too far in interfering with parents and physicians, and noted that it will cut off care for transgender youth already receiving treatment. He said he would have signed the bill if it had focused only on gender confirming surgery, which currently isn’t performed on minors in the state.

The ban was enacted during a year in which bills targeting transgender people have advanced easily in Arkansas and other states. Hutchinson recently signed legislation banning males who claim to be females from competing in womens sports, a prohibition that has also been enacted in Tennessee and Mississippi this year.

Hutchinson also recently signed legislation that allows doctors to refuse to treat someone because of moral or religious objections.
