WHITE PLAINS, N.Y. — Hillary Clinton will be back on the campaign trail Thursday after spending several days at home recovering from pneumonia.

Campaign spokesman Nick Merrill says Clinton will resume normal campaign activities later this week. She is scheduled to address the Congressional Hispanic Caucus Institute dinner in Washington on Thursday evening and appear Friday on “The Tonight Show.”

Clinton’s doctor diagnosed her with pneumonia on Friday and recommended she take five days off to rest, Clinton told CNN. Her campaign didn’t disclose the illness until Sunday, after video showed her stumbling and being supported by aides after abruptly leaving a 9/11 memorial service in New York City.

Merrill said the Democratic nominee spent Tuesday reading briefing material, calling aides and watching President Barack Obama campaign on her behalf in Philadelphia. Clinton had planned to campaign today in Las Vegas. Former President Bill Clinton will headline that event in her place.
