LANSING, Mich. — Senate Majority Leader Mike Shirkey says he tested positive for the coronavirus two days before Christmas and recovered at home. The Clarklake Republican, who publicly announced the infection three weeks after learning of it, is at least the 13th legislator with a positive test. A 14th died from a suspected case in March. Shirkey experienced a fever and fatigue. He believes he was exposed Dec. 19, a day after the Senate ended voting for the year. He visited the House on Dec. 21, appearing to remove his mask while listening to a farewell speech.
