JAMAICA, Iowa (AP) — The central Iowa town of Jamaica is set to appoint a new mayor after its previous mayor was arrested earlier this month on charges related to marijuana found growing in her basement. Acting mayor Tim McDermott tells the Des Moines Register that city leaders are expected to appoint a new mayor at a meeting Monday. Former mayor LaDonna Kennedy and her husband, Randy Kennedy, were arrested Jan. 16 after sheriff’s deputies found marijuana plants in the home.

WASHINGTON (AP) — The clearest path for Democrats to reclaim the White House runs through the upper Midwest, and the party could soon have multiple presidential contenders who have deep roots in the region. The two biggest Midwestern Democratic names in the mix for 2020 are Sens. Sherrod Brown of Ohio and Amy Klobuchar of Minnesota. They’ve succeeded in states where it’s critical to appeal to rural and working-class voters _ groups Democrats are eager to court as they work to defeat President Donald Trump.

CHICAGO (AP) — The painfully cold weather system that put much of the Midwest into a historic deep freeze is expected to ease Thursday, though temperatures could still tumble to record lows in some places before the region begins to thaw out. Disruptions caused by the cold will persist, too, including power outages and canceled flights and trains. Crews in Detroit will need days to repair water mains that burst Wednesday, and other pipes can still burst in persistent subzero temperatures.

URBANDALE, Iowa (AP) — An Urbandale police sergeant is suing the city, saying he suffered harassment, discrimination and retaliation for the post-traumatic stress disorder he suffered in the wake of the 2016 ambush killings of a colleague and a Des Moines officer. The Des Moines Register reports that Sgt. Mark Jorgensen was one of the first responders on the scene when Urbandale Officer Justin Martin was shot as he sat in his patrol car.
