Rep. Ted Lieu (D - CA) has introduced a bill to ban conversion therapy (aka abusing queer people to make them not-queer) nationwide: HR.2119 - Therapeutic Fraud Prevention Act of 2017. There's a companion bill in the Senate, S.928 - Therapeutic Fraud Prevention Act of 2017. People can contact their reps or senators to thank them for co-sponsoring (the list of cosponsors is available at those links), or urge them to vote for the bills if and when they get out of committee (I'm not 100% clear on how that would happen).
