DES MOINES, Iowa (AP) — A Democratic state lawmaker says she has tested positive for COVID-19 and thinks she was infected with the virus at the Iowa Capitol, where Republicans have refused to mandate masks or require people to disclose positive cases. The announcement by Rep. Amy Nielsen of North Liberty on Saturday night marked the first confirmed case among legislators, but there have been three other positive cases among people associated in the House since the legislative session began three weeks ago. One of those additional cases was announced by the House’s chief clerk Saturday. House Speaker Pat Grassley says he cannot force members to wear masks. House rules do require men to wear a tie and jacket when in session and blue jeans are prohibited.

DES MOINES, Iowa (AP) — Iowa reported a record 250 deaths linked to the coronavirus Sunday, which is the biggest one-day increase the state has recorded. The state reported 4,901 deaths linked to COVID-19 on Sunday morning. That was 250 more than what the state reported Saturday, and the figure is significantly higher than the average of 23.43 deaths reported per day over the past week. But the 250 deaths reported Sunday didn’t occur within the last 24 hours. The deaths included many from the end of December and early January because it often takes more than a week for deaths to be added to the state totals after a person has died.

IOWA CITY, Iowa (AP) — Prosecutors have dropped trespassing charges against an activist who secretly recorded Iowa’s largest pork producer using heat to kill hundreds of pigs last year as the pandemic devastated the industry. Matt Johnson, an activist with the group Direct Action Everywhere, had been scheduled to stand trial Monday in Grundy County, Iowa, on two counts of trespassing at Iowa Select Farms properties. County prosecutors dismissed the charges Thursday at the request of Iowa Select, whose personnel had been subpoenaed to testify. A company spokeswoman says it “cannot be distracted by individuals who choose to break the law and grandstand.” Johnson is an Iowa native who now lives in Berkeley, California. He says the company is “desperate to conceal their abhorrent and criminal conduct.”
