Democratic Kansas governor Laura Kelly defied the Trump administration by vetoing a bill that would have banned gender-affirming care for minors.

Kansas’s Senate Bill 63 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.

The state's GOP-controlled legislature’s members had expected Kelly’s action because she vetoed two similar bills previously.

However, votes last month suggested that backers of a Kansas ban have the legislative supermajorities needed to override Kelly’s veto.

Senate President Ty Masterson has said the upper chamber 'will swiftly override her veto before the ink from her pen is dry.'

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.

Supporters argue that a ban would protect vulnerable children from what they’ve often described as a radical ideology about gender .

Transgender youth and their parents have said such care often lessens depression and suicidal tendencies.

Kelly chastised lawmakers in her veto message for what she said was their attempt to interfere with parental rights and in medical decisions.

'It is disappointing that the Legislature continues to push for government interference in Kansans' private medical decisions instead of focusing on issues that improve all Kansans' lives,' Kelly said in a statement.

'Infringing on parental rights is not appropriate, nor is it a Kansas value,' Kelly added.

'As I've said before, it is not the job of politicians to stand between a parent and a child who needs medical care of any kind. This legislation will also drive families, businesses, and health care workers out of our state, stifling our economy and exacerbating our workforce shortage issue.'

The bill easily passed the senate last month, in a 32-8 vote.

President Trump has completed his electoral campaign promise to order the federal government to acknowledge only two genders - male and female.

Trump issued an executive order on the day his second term began that called for 'restoring biological truth to the federal government' and signed another on Wednesday titled ' Keeping Men Out of Women's Sports.

Before his elections, at least 23 had already either banned or restricted gender-affirming care.
