Robert Kraft says he needs an elevator in his $43 million mansion in Southampton, New York, for medical reasons, but authorities aren’t buying it.

Kraft claims he has «mobility issues,» but authorities said the 81-year-old has been seen playing golf and tennis.

Patriots team doctor Mark D. Price said Kraft has «progressive knee pain» that makes the lift a necessity under the Americans with Disabilities Act. Price believes the knee problem is a «medical disability.»

Kraft wants to build the elevator in such a way that the exterior is visible outdoors, but a local review board wants to prevent that. An indoor elevator would cost $2.47 million.while an exterior elevator that Kraft prefers would cost $1.16 million.
