(AP) — Kansas Gov. Sam Brownback has vetoed legislation that would have allowed limited expansion of charity raffles.

The Republican governor said Thursday he determined that the bill violated the Kansas Constitution’s provisions on lotteries and gambling.

Brownback says he supports the Legislature’s intent to allow limited raffles, but he suggested that lawmakers should seek a constitutional amendment instead.

The vetoed bill also had provisions amending a state law on DNA sampling and a sentencing rule for firearms violations.

Brownback signed six bills Thursday, including one establishing “Celebrate Freedom Week” in public schools and amending a law on bullying in schools. The measure would also let school districts use certain unencumbered funds for certain general operating expenses.
