Republicans in the Florida delegation -- U.S. Sen. Marco Rubio, U.S. Reps. Gus Bilirakis, Vern Buchanan, Carlos Curbelo, Ron DeSanits, Mario Diaz-Balart, John Mica, Jeff Miller, Rich Nugent, Tom Rooney, Dennis Ross and Ted Yoho -- waded into the fight over Medicaid expansion on Wednesday, sending a letter to President Barack Obama urging him not to stop the Low Income Pool (LIP) program in Florida. Sources in the Obama administration tell Sunshine State News that HHS has not pulled the plug on LIP funding for Florida even as LIP will not be renewed in its current form.
