Collins, a Republican, said earlier this week she was "leaning no" on the bill.

She said she has not seen anything "to contradict" analysis showing cliffs in Graham-Cassidy funding that would kick in after 2026, and that changing the funding formula for Medicaid would be harmful to many states, including Maine.

"We were on our way to producing a bipartisan bill that would have addressed some of these problems".
Republican Sen. Susan Collins said Friday that she is leaning toward voting against the latest attempt to repeal and replace the Affordable Care Act, citing the bill's potential to increase premium costs for individuals with preexisting conditions.
Republican senators have until September 30 to push a repeal bill through.
