JEFFERSON CITY, Mo. (AP) – Gun control advocates and gun rights supporters are fanning out through the Missouri Capitol, lobbying lawmakers on a bill that would allow most people to carry concealed weapons without needing permits.

Missouri lawmakers are to consider Wednesday whether to override Gov. Jay Nixon’s veto of the high-profile legislation.

The National Rifle Association set up shop in the Rotunda between the House and Senate and dispatched scores of volunteers to talk to lawmakers in support of the legislation. The organization distributed signs saying, “NRA. Stand and Fight.”

Meanwhile, about 150 people rallied with the Missouri chapter of Moms Demand Action for Gun Sense in America. Participants spoke about family members who were fatally shot, and chapter leader Becky Morgan says the group will oppose lawmakers who vote to enact the bill when they’re up for election.
