Texas state senators have voted to allow concealed handgun license holders to carry their weapons into public college classrooms. Monday’s vote is a major push on an issue that had stalled despite overwhelming support from lawmakers in the Republican-dominated Legislature. Senator Jeff Wentworth, Republican of San Antonio, had been unable to muster the votes he needed under Senate rules to pass the issue as its own bill. After several failed attempts, Monday’s vote tacked the measure onto a universities spending bill.
