Clinton will return to campaigning Thursday after canceling a West Coast trip to recover from a bout of pneumonia, her spokesman Nick Merrill said in an email Tuesday.
Merrill said Clinton spent the day at her home in Chappaqua, N.Y., on the phone, "catching up on reading briefings" and watching President Obama on TV as he campaigned for her in Philadelphia.
Clinton has been sidelined with pneumonia since abruptly leaving a 9/11 memorial event Sunday. The campaign later revealed that she had been diagnosed with the illness on Friday.
She had planned to campaign in Las Vegas on Wednesday and former president Bill Clinton will headline the event in her place, the Associated Press reported.
