Gianforte, who had received his first COVID-19 shot last week, received a positive test result Monday after deciding to take the test “out of an abundance of caution” as he was exhibiting mild symptoms a day prior, his office said in a statement.

At his doctor’s orders, the 59-year-old Republican governor will be isolating for 10 days. His office said his wife, Susan Gianforte, was exhibiting no symptoms and was awaiting test results.
