Adding more drama to a $5 billion budget standoff between Republican legislative leaders, Gov. Rick Scott reversed course on his one-time support for providing health coverage for low-income Floridians as part of the federal health care law known as Obamacare.

Scott blamed his rejection of a state Senate plan on a distrust of the federal government, the result of an apparent breakdown in negotiations between his administration and federal officials over a program that pays hospitals and health providers for unreimbursed care. The feds contribute at least $1.3 billion a year toward the Low Income Pool, or LIP, program.

The U.S. Centers for Medicare & Medicaid Services last year gave the state a one-year extension on LIP, set to expire on June 30 unless Scott and federal officials reach a new agreement. But the Obama administration is unwilling to renew the program in its current form.
