Former President Bill Clinton will be filling in for Hillary Clinton at a presidential campaign event in Southern Nevada on Wednesday.

Originally, the former first lady and secretary of state had planned to be at the College of Southern Nevada Cheyenne Campus in North Las Vegas to talk about her plans for the economy. The former president will be campaigning on her behalf Wednesday, an aide confirmed Monday.

Hillary Clinton was told to adjust her schedule and rest after becoming overheated Sunday at a 9/11 event in New York.

Her doctor also said Clinton had a bout with pneumonia and has been put on antibiotics.

He will headline a California fundraiser on Tuesday in her place.
