Topeka ? Gay rights supporters in Kansas are demanding that Gov. Sam Brownback cancel plans to participate in an August prayer rally in Texas organized by a conservative evangelical Christian group.

About 30 people participated in a rally Friday at the Statehouse.

Brownback has accepted an invitation from fellow Republican Gov. Rick Perry of Texas to attend the Aug. 6 event in Houston.

It’s organized by the American Family Association, a Mississippi group best known for objecting to what it sees as indecency on television. The group opposes gay marriage and protests actions it views as promoting homosexuality.

Brownback spokeswoman Sherriene (shuh-REEN’) Jones-Sontag says the governor will go to the rally if his schedule permits it. As for Friday’s protest, she says Brownback respects the right of Kansans to demonstrate peacefully.
