President Donald Trump's wife Melania is canceling a rare joint appearance with him at a campaign rally Tuesday due to a "lingering cough" following her infection with the coronavirus, a spokeswoman said. "Mrs Trump continues to feel better every day following her recovery from COVID-19, but with a lingering cough, and out of an abundance of caution, she will not be traveling today," Stephanie Grisham said in a statement. The first lady's appearance with Trump in Erie, Pennsylvania, was to have been her first at a campaign rally in more than a year. sms/ft
