DES MOINES (AP) — Anti-abortion advocates and lawmakers rallied in the Iowa state capitol Monday, but many of them said changing state abortion laws remains a challenge given the politically divided Legislature.

Gov. Terry Branstad and Lt. Gov. Kim Reynolds were among the speakers at the event, which was sponsored by nine advocacy groups. Branstad told the roughly 100 attendees that the founding fathers had purposely spelled out “life, liberty and the pursuit of happiness” in the Declaration of Independence. Reynolds said the anti-abortion movement supports women.

“I think they like to sometimes classify a pro-life woman as not really giving women a choice. I’m standing strong for those who can’t protect themselves,” she said.
