Clinton to Call Into Fundraiser Due to Pneumonia

In the heart of the general election season, Hillary Clinton has decided to take two days off and possibly more after a diagnosis of pneumonia by her doctor, Lisa Bardack, who suggested Clinton "rest and modify her schedule."

Clinton was scheduled to fly to San Francisco Monday for a fundraiser. That event is still taking place, but Clinton won't be there, instead calling in from her house in Chappaqua, New York.

"If it was up to her, she would be traveling to California today," said Clinton press secretary Brian Fallon on MSNBC's "Andrea Mitchell Reports."

"This morning she's already been calling staff. She made phone calls this morning. She will be dialing into that finance event on the West Coast later today," Fallon said. "I expect by the middle to later in the week, she'll be on the campaign trail."

In addition to the San Francisco fundraiser, Clinton will miss two fundraisers Tuesday in Los Angeles including one at the home of Seth MacFarlane with a planned performance by Lionel Richie. The other fundraiser is hosted by Diane von Furstenberg and Barry Diller, costing $100,000 per couple. It's unclear whether Clinton will call in remotely to those events.

"If it was up to her, she would be out in the next five minutes," said Clinton campaign manager Robby Mook.

On Sunday, Clinton told reporters she was "feeling great" when she left the Manhattan apartment of her daughter, Chelsea Clinton, after becoming "overheated" at a 9/11 anniversary ceremony.

Hours later, Bardack released a statement that she diagnosed Clinton with pneumonia on Friday and put her on antibiotics. After the diagnosis, Clinton kept a packed schedule Friday that included a national security roundtable with a few questions from the press, two fundraisers and two taped interviews.

"It is important to take good care of yourself. All of us are frequently in awe of the schedule that our own boss keeps," said Fallon.

Clinton is scheduled to attend a campaign event in Las Vegas on Wednesday, but her campaign has not said whether she will make that trip.
