"I am committed to ensuring that important provisions of the ACA, such as covering those with pre-existing conditions, continued support for Medicaid expansion, coverage for dependents and no lifetime limits, and funding for Planned Parenthood remain intact," she said in the letter obtained by Politico for a report Friday.

Asked about the letter this week, the GOP senator told the newspaper she is a "strong proponent [of Planned Parenthood] and I will fight to keep the funding in." She declined to make promises on legislation she said she hasn't seen.

The letter comes as Republicans scramble to form an ObamaCare repeal bill that will be able to pass the Senate, as Republicans can only afford two defections and have Vice President Pence cast a tie-breaking vote.

Murkowski is a critical swing vote in the ongoing healthcare debate, which means her position on Planned Parenthood could play a role in shaping the final bill.

The Alaska senator has said in the past she does not support defunding the organization as a part of the repeal effort.

“Taxpayer dollars should not be used to pay for abortions, but I will not vote to deny Alaskans access to the health services that Planned Parenthood provides,” she said earlier this year.

Federal law already prohibits taxpayer dollars from being used to pay for abortions.
