Representative Samantha Sencer-Mura leads action after Republican speaker rescinds promise to bring bill to vote

Democratic state representatives in Minnesota staged an overnight sit-in in their house chamber on Thursday after the Republican speaker failed to put a gun violence prevention bill up for a vote.

Samantha Sencer-Mura, a Democratic representative from Minneapolis, first announced the plan on Wednesday from the floor of the state’s house of representatives, giving the speaker, Lisa Demuth, a candidate for governor, 24 hours to give the bill a vote before the sit-in would start.
