Democratic presidential nominee Hillary Clinton will return to the campaign trail Thursday, a spokesman said Tuesday, according to CBS News.

Clinton had earlier in the week canceled three days’ worth of events due to pneumonia.

On Sunday, Clinton was abruptly removed from a 9/11 memorial event in Manhattan when she suffered what senior law enforcement officials described as a “medical episode.”

Clinton's doctor later revealed that she was suffering from pneumonia, with which she was diagnosed on Friday, and that the incident at the memorial was a result of dehydration and overheating.

In an interview with CNN Monday night, Clinton said she was feeling “much better” and that she hadn’t disclosed the pneumonia diagnosis because she “didn’t think it was going to be that big a deal.”

She also admitted she had ignored doctor's orders to rest.

Clinton was slated to appear at a series of fundraisers in California Monday and Tuesday, and to speak in Nevada on Wednesday. Her Monday events were canceled entirely, while her husband, former President Bill Clinton, filled in for her Tuesday and will do the same in Nevada on Wednesday.

Spokesman Nick Merrill said she kept busy while recuperating at home Tuesday. “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 in a statement to reporters quoted by CBS News.

The Clinton campaign has not yet released her schedule for Thursday or the rest of the week. She has said she will release additional information about her health in the coming days.
