Gov. Jeb Bush said Thursday he might ask a state attorney to investigate allegations that Terri Schiavo's husband waited more than an hour to call 911 after her 1990 collapse. "There's some doubt about when she did collapse and how long it took ... for the 911 call to be made," Bush said. "Which I think is worthy of some investigation. I don't know what form it would take." Bush said he might ask Bernie McCabe, state attorney for Pinellas-Pasco, to look into the issue, but that would have to wait until McCabe returned from vacation.
