JEFFERSON CITY, Mo. (AP) — Missouri House Speaker Tim Jones says he wants to try to override Gov. Jay Nixon’s veto of a gun-rights bill passed by the Legislature.

Nixon announced Friday that he had vetoed the bill. It sought to nullify various federal gun laws and would have allowed federal agents to be charged with misdemeanor crimes for trying to enforce federal gun control laws in Missouri. Journalists also could have faced charges for publishing the names of gun owners. Nixon said that would have violated federal free speech rights.

Similar legislation attempting to nullify new federal gun laws recently passed in Kansas.

Jones said Friday that he is “shocked and astounded” by Nixon’s veto. He believes “a supermajority of Missourians” want lawmakers to override the veto.

An override would require a two-thirds vote in both the House and Senate during a September session.
