SIDNEY, Iowa (AP) — Rebuffing President Donald Trump and Republican leaders on the GOP health care bill seemed like a major political misstep for Iowa Rep.

DES MOINES, Iowa (AP) — Iowa is set to become the latest state to allow gun owners to keep firearms at their side while visiting the state Capitol. It’s a move that’s raised questions about how security workers would deal with armed visitors. Republican Gov. Terry Branstad plans to signs the measure Thursday as part of a wide-ranging gun bill. It will mirror similar activity at statehouses around the U.S. in recent years.

IOWA CITY, Iowa (AP) — The owner of a gun that a 4-year-old boy used to kill himself last summer in Iowa has been charged with illegally owning the firearm after telling police he regularly used marijuana. Twenty-nine-year-old Daniel Henriksen pleaded not guilty Wednesday to being an unlawful drug user in possession of a firearm. He wasn’t there when Jayden Choate shot himself June 17 in Henriksen’s trailer in Elgin.
