“It makes absolutely no sense to eliminate federal funding for Planned Parenthood,” Collins told ABC’s George Stephanopoulos on “This Week.”

The moderate Republican’s comments come just days after Senate Republicans revealed proposed legislation to repeal and replace ObamaCare, which would defund the nonprofit, which provides women’s health services and abortions.

The bill moves to defund Planned Parenthood for a year by blocking Medicaid reimbursements.

“There are already longstanding restrictions on the use of federal funds for abortion, so this is not what this debate is about. And Planned Parenthood is an important provider of healthcare services, including family planning and cancer screenings for millions of Americans, particularly women,” she continued.

“I am optimistic we'll prevail on that issue,” Collins said, referring to amending the legislation.

Planned Parenthood distributed the clip of the GOP lawmaker praising the organization on Sunday.

Collins is not the only Republican who has criticized various parts of the bill.
