Massachusetts Senator Edward Kennedy (D) was rushed from the Kennedy compound in Hyannisport (Cape Cod) to Mass General Hospital with stroke-like symptoms.
The 76-year-old leading Democrat and prominent supporter of Presidential candidate Barack Obama, was rushed to a Cape Cod hospital early in the morning, but was airlifted to Mass General Hospital shortly after.
Last October, Ted had surgery at Mass General to unclog a partially blocked carotid artery in his neck. It was discovered during a routine back and spine check.
Doctors said a blocked carotid artery can lead to a stroke and death.
Ted Kennedy is the second-longest serving member of the Senate.
An Obama's spokesperson said Barack extends his prayers and best wishes to the Kennedy family.
