Republican presidential candidate Rudy Giuliani was admitted to a hospital while campaigning in Missouri after experiencing flu-like symptoms – the Associated Press Reports.

Giuliani reportedly felt discomfort after his plane took off from an airport in Chesterfield, Missouri, prompting the aircraft to turn back.
