Here is the latest Michigan news from The Associated Press at 1:40 a.m. EDT

LANSING, Mich. (AP) — Democratic Sen. Gary Peters of Michigan reports that his campaign raised $7.4 million in the first half of October. The first-term incumbent is locked in a competitive, expensive race with Republican challenger John James. Total spending is expected to top $100 million in the contest that will affect which party takes the Senate majority, which is now held by the GOP. Peters has led or been slightly ahead in recent polling. Peters’ campaign manager Dan Farough says the latest fundraising total makes “clear that the momentum and grassroots energy” is with the senator.

LANSING, Mich. (AP) — Gov. Gretchen Whitmer has signed into law legal protections for Michigan businesses and other employers that are sued by infected people despite having followed all coronavirus safety protocols. She also codified rules shielding hospitals and other medical providers from pandemic-related lawsuits except in cases of gross negligence, from late March to mid-July, in the wake of the state Supreme Court invalidating her executive orders. Another new law signed Thursday, which mirrors one of the orders, prohibits employers from retaliating against workers who stay home because they have been exposed to COVID-19.

LANSING, Mich. (AP) — Michigan State University is planning to increase in-person classes and open dorms starting in January, but will skip spring break. MSU President Samuel Stanley Jr. said in a letter Thursday to students, faculty and staff that the school will offer 400 in-person classes for the spring semester, up from 40 in the fall. To accommodate students, 2,500 single occupancy residence-hall spaces will be opened. MSU was the first public university in Michigan to halt in-person classes in March and advise students to leave East Lansing and attend from home. However, the college town has seen several student—caused spikes in coronavirus cases.

EAST BAY TOWNSHIP, Mich. (AP) — State environmental regulators are looking into whether some residents in a northern Michigan community have been using drinking water contaminated with chemicals. The Traverse City Record-Eagle reports that groundwater monitoring wells have returned elevated results for PFAS — perfluoroalkyl and polyfluoroalkyl substances. State and local officials are hosting an online town hall meeting Monday night to explain the discovery and the planned investigation in East Bay Township. The 10 monitoring wells were installed this summer. Michigan’s Department of Environment, Great Lakes and Energy wants to test the private water wells of about 20 homes and one business, and about a half-dozen irrigation wells in the area that remain uncapped.
