Pneumonia Sidelines Hillary Clinton During Campaign Trips

Last night Democratic presidential candidate Hillary Clinton canceled a campaign trip to California — after her doctor revealed that Clinton was diagnosed on Friday with pneumonia.

The disclosure about Clinton's health came yesterday, after she stumbled and had to be helped into a van after suddenly leaving a 9/11 memorial service in New York City.

Here & Now's Robin Young speaks with Dr. Robert Kotloff, chairman of the department of pulmonary medicine at the Cleveland Clinic, about what kind of pneumonia Clinton may have and what recovery might be like.
