TALLAHASSEE, Fla. (AP) - Gov. Charlie Crist wants another $100 million from BP.

A day after asking the company for $50 million, Crist sent a letter to BP America President Lamar McKay asking for an additional $100 million - money he said Friday is needed to monitor the threat to Florida's ecosystem.

The initial traces of oil from the BP spill in the Gulf of Mexico washed onto Florida shores for the first time Friday.

Florida has already received $50 million from BP and Crist's newest request would bring the state's total request to $200 million. Crist also said BP would be asked for more.

Crist said the $100 million would pay for evaluating water conditions to help scientists find ways to combat the threats to Florida waters and beaches.
