Missouri lawmakers wrap up annual session

Missouri lawmakers have wrapped up their annual legislative session while passing a bill that could allow teachers to carry guns in the classroom.

The gun legislation was one of dozens of bills that passed Friday. But senators failed to take a final vote on a more expansive bill that would have attempted to nullify some federal gun control laws.

Several significant bills passed before the last day of the session. Lawmakers overrode Gov. Jay Nixon's veto to enact the first income tax rate reduction in nearly a century. They also referred a transportation sales tax to the ballot.

Other bills they passed would triple the waiting period for abortions and overhaul state education and crime laws.

The failed measures included a proposed Medicaid expansion.
