This year's measure not only would ban gender-affirming surgeries, hormone treatments and puberty blockers for minors but also prohibit state employees caring for children from promoting social transitioning for them.
House Minority Leader Brandon Woodard, a Kansas City-area Democrat, acknowledged as much during a recent news conference and said opponents will ask state courts to overturn a ban.
Kansas' Democratic governor on Tuesday vetoed a proposed Republican-backed ban on gender-affirming care for transgender minors.
Votes last month suggested that backers of a Kansas ban have the legislative supermajorities needed to override Kelly's veto.
Supporters argue that a ban would protect vulnerable children from what they've often described as a radical ideology about gender.
