ORLANDO, Fla. -- Florida Gov. Jeb Bush's 25-year-old daughter was found with what was believed to be crack cocaine at a drug rehab center where she was undergoing court-ordered treatment, police said.

If confirmed, it would be Noelle Bush's second lapse since entering rehab and could result in jail.

Police late Monday were called to the Center for Drug Free Living in Orlando, where workers gave them a 0.2-gram rock they said they found in Noelle Bush's shoe, Sgt. Orlando Rolon said.

The rock tested positive for cocaine in a police field test, but Bush was not immediately arrested because police could not get staff members at the rehab center to cooperate and give sworn statements, Rolon said.
