A House resolution introduced last week calls on states to approve laws that prohibit therapies that attempt to alter the sexual orientation or gender identity of LGBT youth.
California Representative Jackie Speier, a Democrat, introduced the Stop Harming Our Kids (SHOK) Resolution of 2015 on Tuesday.
Two states, California and New Jersey, plus the District of Columbia, already prohibit so-called conversion therapy to anyone under 18 years old.
The move comes less than a week after the Obama administration came out in support of such bans.
Speier, a longtime opponents of such therapies, introduced a similar resolution in 2012.
LGBT advocate the National Center for Lesbian Rights (NCLR) last year launched its #BornPerfect campaign, which aims to raise awareness about “the serious harms caused by attempts to change a young person's sexual orientation or gender identity.”
“We applaud Congresswoman Speier for her genuine leadership and commitment to protecting young people and their families from the dangers of these widely discredited practices,” NCLR Executive Director Kate Kendell said in a statement. “We are proud to stand with the congresswoman in urging every state to adopt legislation to ensure that no young person or vulnerable family is exploited by mental health professionals peddling devastatingly harmful psychological practices to fix something in our children that was not broken in the first place.”
