At least 65 demonstrators seeking anti-discrimination protections for gays and lesbians law ringed the third floor rotunda of Idaho's Capitol 10 days after dozens of them were arrested at a previous protest.
Thursday's demonstration didn't include blocking entrances to lawmakers' chambers, the event that precipitated arrests March 3.
Idaho State Police troopers who guard the Capitol observed the silent protest -- the demonstrators covered their mouths with their hands -- but didn't intervene.
Activists are upset lawmakers for eight years have refused to add workplace and housing discrimination protections for gays, bisexuals, lesbians and transgender individuals to the Idaho Human Rights Act.
Republicans have blocked a hearing on a bill this year, over objections from Democrats.
Mike Butts, a spokesman for the group, said "Sadly, we'll feel forced to return."
