DES MOINES, Iowa (AP) — A state judge has struck down Iowa’s restrictive “fetal heartbeat” abortion law. Judge Michael Huppert on Tuesday found the law unconstitutional.

Joni Ernst says she turned down Donald Trump after interviewing to be his running mate, according to a court filing that describes an “extremely painful journey” that led to her divorce from a man she alleges was abusive. The Iowa Republican wrote in an affidavit in her divorce proceeding that after Trump interviewed her in 2016 to join his ticket, “I turned Candidate Trump down, knowing it wasn’t the right thing for me or my family.” She doesn’t explicitly say if he offered her the job.

DES MOINES, Iowa (AP) — Authorities say a Des Moines resident suspected of fatally injuring a pedestrian while driving a stolen car has been charged with first-degree murder.

Police say Bomar was driving the stolen car when he hit 69-year-old Charles Michael Childs and kept going. Childs was found dead two days later inside a tent at a homeless camp.
