Laws allowing concealed guns on college campuses took effect Saturday in several states, including Georgia and Kansas.
In Tennessee, concealed guns may now be carried in a broader range of public buildings and bus stations. And in Iowa, permit holders are now able to carry concealed guns in the Capitol.
Jennifer Baker, a spokeswoman for the National Rifle Association Institute of Legislative Action, described 2017 as another "successful year for gun rights."
The new laws continue a pattern of the expansion of gun rights in GOP-controlled states.
The firearms policies are among scores of laws that took effect Saturday, along with the start of the new fiscal year in many states. Some of those laws continue a recent trend of states taking the initiative to fix aging roads and address the drug overdose epidemic.
