Mrs. Trump’s chief of staff Stephanie Grisham said the first lady “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,” Grisham said in a statement.
The statement comes ahead of President Trump’s scheduled “Make America Great Again!” rally in Erie, Pa., later Tuesday – just two days before the candidates will face off for the second and final presidential debate on Thursday night.
Mrs. Trump’s last public appearance was during the Sept. 29 presidential debate in Ohio. She and President Trump announced in early October that they had both tested positive for the virus. Their results came after close aide Hope Hicks also tested positive.
The first lady announced last week that she had tested negative.
