Hillary Clinton is back!

The Democratic presidential candidate will begin campaigning again Thursday, her spokesman Nick Merrill told PEOPLE on Tuesday.

“Secretary Clinton remains at home. She has spent the day catching up on reading briefings, making calls, and she watched President Obama’s speech
in Philadelphia on TV,” he said. “We will resume campaign travel on Thursday with a speech in Greensboro, N.C. where Secretary Clinton will discuss her vision for an America that is stronger together.”

Clinton abruptly left a 9/11 memorial event Sunday and it was later revealed that she had been diagnosed with pneumonia on Friday.

Clinton called in to Anderson Cooper‘s CNN show on Monday, saying she didn’t think her pneumonia diagnosis was “going to be that big a deal.”

“It’s just the kind of thing that, if it happens to you and you’re a busy, active person, you keep moving forward,” she said of her decision to keep her Friday diagnosis hidden until Sunday.

Clinton had planned to appear in Las Vegas on Wednesday. Former President Bill Clinton will take her place at the event, according to the Associated Press.
