The Senate changed its mind Thursday on a bill designed to prevent discrimination against school students by other students or teachers.

Senate Bill 2216, which passed the Senate last month, 27-20, came back for another vote Thursday after the House amended it.

This time, the Senate killed the bill, 25-16, mostly along party lines. Two Republican senators who joined the Democratic caucus in voting for it again were Ray Holmberg of Grand Forks and Tim Flakoll of Fargo.
