TAMPA, Fla. (AP) - Attorney General Bill McCollum plans to talk

to the media about developments in the lawsuit challenging

President Barack Obama's health care overhaul.

McCollum's office said the news conference in Tampa Friday

afternoon will coincide with the filing of an amended lawsuit.

At least 17 other states joined Florida in a federal lawsuit

filed in March after Obama signed his 10-year, $938-billion health

care bill into law. The Republican-controlled Florida Legislature

passed a bill last month backing the suit.

A federal judge said he intends to fast track the action.
