An effort in Montana to outlaw gay protections laws appears to have fizzled in the Senate after winning approval in the House, the AP reported.

Republican Representative Kristin Hansen's bill sought to prohibit local governments from enacting laws banning discrimination beyond those classifications listed in the state's Human Rights Act, which does not include sexual orientation or gender identity.

The bill's target was Missoula, the state's second largest city, which approved such an ordinance last year.

The measure enjoyed overwhelming support in the House, where sixty GOP members united to overcome the objections of 32 Democrats and 7 Republicans in approving the legislation earlier this month.

Senator Jon Sonju told the AP that the bill has been returned to the Local Government Committee he chairs. The bill cleared the committee last week.

Sonju said the measure was shelved because it does not have the support of Senate leaders.

Last week, the transgender rights group Transgender Legal Defense & Education Fund called on the Montana Senate to reject the proposal, arguing that the law was motivated “solely by animus towards transgender and gay people.”
