TALLAHASASEE, Fla. (AP) - Florida's investment chief says the state retirement fund is one of the nation's healthiest.

Ash Williams' report Tuesday to Gov. Charlie Crist and two Cabinet members who oversee the fund contrasts with an ad by the Republican Party of Florida suggesting state pensions are at risk.

The ad is aimed at Democratic gubernatorial candidate Alex Sink, who sits on the board as Florida's chief financial officer.

She fired back saying her Republican rival, Rick Scott, who approved the ad, has been irresponsible by "scaring our retirees."
