The Senate will vote as early as Monday on a bill to strip Planned Parenthood of federal funding, a largely symbolic vote causing pain for centrists in both parties and drawing fire from conservatives who say it won’t satisfy their quest to put the organization out of business.

The bill isn’t expected to garner the 60 votes needed to advance, as nearly all Democrats object to it. Its defeat, however, won’t end the effort to cut off federal money for Planned Parenthood.

The effort gained traction after an antiabortion group began releasing undercover videos depicting Planned Parenthood officials and personnel discussing how tissue from aborted fetuses is provided for medical research. The antiabortion group, Center for Medical Progress, released a fourth video on Thursday and has said there are more to come.

When lawmakers return from their August recess, the issue could entangle government funding. Conservative Republicans say they will demand the defunding plan be folded into a spending bill needed to avoid a government shutdown this fall.

Planned Parenthood received federal and state grants and reimbursements of about $528.4 million last year, mostly from Medicaid, the federal-state health program for the poor. Under federal law, federal dollars cannot be spent on abortions, but abortion opponents argue that Medicaid reimbursements and family-planning money help support an organization that is the nation’s leading abortion provider.
