Gov. Asa Hutchinson of Arkansas vetoed a bill on Monday that would make it illegal for transgender minors to receive gender-affirming medication or surgery — a rare Republican rejection amid the growing conservative effort to restrict transgender people’s health care and participation in society.
The Arkansas State Legislature could override Mr. Hutchinson’s veto of the bill, known as H.B. 1570. Republicans hold large majorities in both chambers and passed the bill last month with mostly party-line votes: 70 to 22 in the House and 28 to 7 in the Senate.
