Here is the latest Michigan news from The Associated Press at 3:40 p.m. EST

LANSING, Mich. (AP) — Michigan has launched the statewide rollout of a voluntary, free coronavirus app that notifies users if they have potentially been in close contact with infected people. Monday’s announcement comes weeks after the state began piloting the technology in Ingham County, including at Michigan State University. State Health and Human Services Director Robert Gordon is encouraging all Michiganders to download the app onto their smartphones, especially as COVID-19 cases and related hospitalizations are surging after an initial wave subsided last spring. App users who possibly were within 6 feet of infected people for at least 15 minutes are notified.

WARREN, Mich. (AP) — Warren City Hall in suburban Detroit has been closed to the public due to a spike in positive COVID-19 cases among city employees in several departments. Mayor James Fouts says the building will be closed this week and disinfected. Confirmed virus cases also are up at the city’s police department and district court which also are being disinfected. Fouts said Warren currently has more employees testing positive for the virus than at any other time during the coronavirus pandemic. Steps are being taken to make sure all city employees receive testing. Virus cases have been going up across Michigan. On Saturday, state health officials reported 6,225 new coronavirus infections.

PORT HURON, Mich. (AP) — A 59-year-old man has been arraigned on charges accusing him of setting off explosives in trash cans at the eastern Michigan hospital where he works. The Detroit News reports that Michael Patrick Barna, of Cylde Township, faces charges of explosives violation of a vulnerable target and explosives with intent to frighten. His arraignment was Sunday and his next scheduled hearing is set for Nov. 17. Police say no one was hurt and there was no major damage when three incendiary devices detonated Wednesday afternoon at McLaren Port Huron Hospitals, but the blasts “frightened and terrorized staff inside the hospital.”

UNDATED (AP) — Republican surrogates for President Donald Trump have resumed their legal fight to try to stop the vote count in key battleground states, including Pennsylvania and Michigan. But they face long odds given the Electoral College tally and recent court rulings that found no evidence of widespread vote fraud. Some Republican state officials are invoking the Trump mantra that only “legal votes” should be counted before the election is certified. Others are coming forward to urge voters to accept the results. Democratic President-Elect Joe Biden has claimed the White House and started working on his agenda, although Trump has yet to concede the race.
