A relative of former President Bush died of a heart attack while visiting his seaside vacation home in Kennebunkport, Maine Tuesday, Fox News confirmed.

Paramedics transported the husband of the former president's cousin to the Southern Maine Medical Center in Biddeford, Maine, Fox News sources confirmed.

The patient had been a guest of the 41st president and his wife, Barbara Bush, when he suddenly became ill.

"President and Mrs. Bush are both fine. It was not one of them," Kristan King, a spokeswoman for Barbara Bush, told The Associated Press from Kennebunkport. "It was one of their houseguests here staying with them."
