WASHINGTON — (CNN) Hillary Clinton will return to the campaign trail Thursday, spokesman Nick Merrill said.

The Democratic nominee, who was recently diagnosed with pneumonia, spent Tuesday at her home in Chappaqua, New York, where she watched President Barack Obama’s stump speech in Philadelphia on her behalf, Merrill said.

She has no events Wednesday.

“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.
