BATON ROUGE, La. — Louisiana Senate failed Tuesday to override Gov. John Bel Edwards’ veto of a gun-related bill. The legislation Edwards vetoed would have done away with a requirement for training to get a concealed-carry permit. A group of Louisiana law enforcement officers came out against the bill and in support of the veto. Supporters say the legislation asserts the Second Amendment. Those against the bill say the required training is reasonable and supported by the majority of Louisiana residents. The vote was 23-15 in favor of overriding the veto — not enough to override the veto.
