JEFFERON CITY, Mo. (AP) — Missouri's Republican-led Legislature used its supermajority Wednesday to significantly loosen the state's gun laws and potentially tighten its voting requirements as lawmakers overrode numerous vetoes of Democratic Gov. Jay Nixon.

The sweeping guns legislation would allow most adults to carry concealed weapons without needing a permit while also expanding people's right to defend themselves both in public and private places. The elections law change would require people to show a government-issued photo ID at the polls starting in 2017, if voters also approve a proposed constitutional amendment on the November ballot.

Both measures passed with more than the required two-thirds majority in each chamber as Republicans shut off Democratic discussion and enacted the laws on largely party-line votes.
