Gov. Tom Wolf has tested positive for COVID-19 for the second time, according to a post on his social media. “My symptoms are mild,” Wolf wrote. “I’m grateful that I recently got my second vaccine booster.” Wolf said he is isolating at home, according to CDC guidance. In December 2020, Wolf tested positive for the virus but was asymptomatic. He was testing negative in the following days, his office said at the time. It was unclear Monday how Wolf would be handling upcoming engagements.
