Kansas Gov. Sam Brownback has signed legislation restricting the use of state funds to promote or oppose gun control policies.

The measure signed Friday takes effect in July. It passed the Legislature this year with strong support from gun rights advocates.

The new law will prohibit local governments and school districts from using funds they get from the state to hire lobbyists to influence Kansas legislators on gun control issues. Also, neither the state nor local governments could hire Washington lobbyists to influence federal officials.

The measure also says no state funds can be used for materials or advertising on gun control issues.

Critics contend the new law will violate public officials’ free speech rights. But supporters said those officials still can speak out without using state funds.
