ANAMOSA, Iowa (AP) — Officials have lifted a bottled water advisory in Anamosa after determining a chemical mistakenly added to the water supply was harmless at low concentrations. The Department of Natural Resources lifted the advisory Monday evening after determining the chemical was triethanolamine, used mostly in the cosmetic and drug industries. One to three gallons of the chemical were mixed into about 750,000 gallons of water storage, which diluted the chemical to a harmless level.

DES MOINES, Iowa (AP) — Iowa Gov. Terry Branstad says the Republican Party must come together and support Donald Trump’s candidacy for president. The Republican governor said Monday that GOP leaders need to accept that Trump will be the party’s nominee for president and work to defeat Hillary Clinton, the likely Democratic nominee. He said there’s “some time” to mend internal division within the party over whether to support Trump.

DES MOINES, Iowa (AP) — Now that Donald Trump is the presumptive Republican presidential nominee, supporters of President Barack Obama’s Supreme Court pick believe they have a winning argument to get the GOP-led Senate to act. Judiciary Committee Chairman Chuck Grassley opposes confirmation hearings or votes on Judge Merrick Garland until Americans elect the next president. But with Trump the likely nominee, Grassley is under new pressure from Democrats and the White House.

IOWA CITY, Iowa (AP) — The lawyer for a man convicted of first-degree murder in the shooting death of a woman in a Coralville mall has requested a new trial, claiming prosecutors didn’t follow court rules. Alfredo Parrish filed the motion last week on behalf of his client 23-year-old Alexander Kozak. A jury in April found Kozak guilty of killing 20-year-old Andrea Farrington at the Coral Ridge Mall on June 12.

The Mills County Sheriff’s Office, Monday, said two people were arrested over the weekend. On Saturday, 56-year old Verner Jay Moore, of Emerson, was arrested for Domestic Abuse Assault and Obstruction of Emergency Communications. His bond was set at $1,300. And, on Sunday, 41-year old Justin David Rhea, of Council Bluffs, was arrested for OWI/2nd offense, and Driving Under Suspension. His bond was set at $2,300.

Three accidents were reported in Mills County, as well, with injuries resulting from one of the incidents. Officials say at around 1:50-p.m. Friday, vehicles driven by Jonathan Cochran, of Bellevue, NE., and Logan Allen, of Glenwood, collided in the 5600 block of 221st Street, as a 2015 Dodge driven by Allen, was traveling north and making a left turn into a driveway. A 2013 Harley Davidson motorcycle driven by Cochran, was traveling south and saw the Dodge turning. Cochran applied the brakes causing his cycle to skid. The cycle fell onto its side and collided with the Dodge in the southbound lane. The motorcycle hit a trailer being pulled by the Dodge, that was loaded with horses. Cochran was transported by Glenwood Rescue to a hospital in Council Bluffs, for treatment.

DES MOINES, Iowa (AP) — Iowa Gov. Terry Branstad says Donald Trump should consider U.S. Sen. Joni Ernst as his vice presidential running mate for the upcoming general election. Branstad told reporters Monday the senator from Iowa would be a “great asset” to Trump, the Republican’s presumptive nominee for president. The governor says Ernst’s military record and political background make her an ideal choice for the job.

Branstad made the comments after Sen. John McCain of Arizona voiced support recently for Ernst as a possible VP pick. Branstad says he has not discussed the subject with Ernst, who is serving her first term in the Senate. He says he intends to try to meet directly with Trump before the party’s national convention in July to formally make the case for Ernst.
