Karen Pence

"This morning, Vice President Pence and the Second Lady tested negative for COVID-19."

"Second Lady Karen followed an agreement established between both campaigns prior to the debate."

Pence, who will be renominated as Trump's running mate after on-and-off speculation that he would be dropped from the ticket, is the highest ranking official to address the four-day convention.

She says her husband was not made aware of the policy until after his visit.
