First Lady Melania Trump has been suffering from the effects of a lingering cough due to COVID-19, preventing her from joining husband Donald Trump on the campaign trail, Fox News reported on Tuesday.

Both Melania and Donald Trump were diagnosed with COVID-19 in early October, and though President Trump recovered rapidly and returned to the campaign trail in record time, the first lady has kept a low profile.

According to the FLOTUS’s chief of staff, Stephanie Grisham, Melania “continues to feel better every day following her recovery from COVID-19.”

However, Grisham said that “with a lingering cough, and out of an abundance of caution, she will not be traveling today” to a campaign event in Pennsylvania.

The first lady announced last week that she had tested negative for the virus, but still has not made any public appearances since late September.

President Trump is scheduled to appear at a “Make America Great Again!” rally in Erie, Pennsylvania later Tuesday. With less than two weeks to go until election day, Democrat nominee Joe Biden’s home state appears to be in play, according to new polls.

A Restoration PAC/Trafalgar Group survey released Monday found that Biden’s lead on Trump has shrunk to just 1.1 percent — down from 2.3 percent last week.

Trump is maintaining a brisk campaign schedule ahead of Thursday’s presidential debate, attending nearly half a dozen campaign rallies in just three days.

Biden, on the other hand, called a lid on campaigning on Monday morning, and is not expected to appear in public until Thursday evening’s debate.
