Here is the latest Iowa news from The Associated Press at 3:40 a.m. CDT

DES MOINES, Iowa (AP) — Just two months after a federal court judge struck down Iowa’s existing law meant to discourage investigations of animal abuse on farms, lawmakers are pushing another so-called ag-gag measure that opponents say would likely land them in court again. Civil rights and animal rights groups are surprised Iowa Republican lawmakers would try to pass another law inviting further lawsuits when they haven’t yet completed appeals in the last lawsuit, for which legal bills already likely exceed $200,000.

CEDAR FALLS, Iowa (AP) — About 20 pigs and sheep died after a barn caught fire in Iowa but no one was hurt. The Waterloo-Cedar Falls Courier reports the fire was reported shortly after 6 a.m.

AUSTIN, Texas (AP) — Former Colorado Gov. John Hickenlooper tells a house party in Dubuque, Iowa, that immigration hard-liners have to accept that they won’t be able to drive out everyone who is in the U.S. illegally. Hickenlooper says it would be “crazy” to think that a country founded and defined by immigrants would ever expel 10 million to 11 million people. Hickenlooper launched his bid for the Democratic presidential nomination this week. He is on his first Iowa swing as an official candidate.

DENMARK, S.C. (AP) — Rural America is a stronghold for President Donald Trump and Republicans. But there are Democrats and persuadable voters there who are important to picking the Democratic presidential nominee. Some Democratic presidential candidates are reaching out to rural areas and small towns as they campaign for the 2020 election. Cutting into Republican advantages in the general election could help flip several swing states that gave Trump his 2016 victory.
