The House took the first steps Tuesday toward striking down Missoula's 2010 ordinance that bans discrimination against city residents based on their sexual orientation, gender identity and gender expression. Missoula's Democratic legislators were infuriated by the passage of House Bill 516, by Rep. Kristin Hansen, R-Havre. Her bill passed 60-39 and faces a final House vote before heading to the Senate. Sixty Republicans voted for it. All 32 Democrats voted opposed it, joined by seven Republicans. One Republican was absent.
