From NBC's Mark Murray
The Giuliani campaign announced today that Jeb Bush Jr. -- the son of the former Florida Gov. Jeb Bush, who is President George W. Bush's brother -- has endorsed Giuliani.
But there appears to be a split in the family. Jeb Bush Jr.'s more famous brother -- George P. Bush -- previously endorsed Fred Thompson.
*** UPDATE *** This is the same Jeb Bush Jr. who was caught having sex in a car in a Tallahassee, Fla., mall parking lot in 2000 when he was 16 (no charges were filed) and charged with public intoxication and resisting arrest in Austin, Texas in 2005.
