Republicans in the House of Representatives are mounting an assault on women’s health and freedom that would deny millions of women access to affordable contraception and life-saving cancer screenings and cut nutritional support for millions of newborn babies in struggling families. And this is just the beginning.

The budget bill pushed through the House last Saturday included the defunding of Planned Parenthood and myriad other cuts detrimental to women. It’s not likely to pass unchanged, but the urge to compromise may take a toll on these programs. And once the current skirmishing is over, House Republicans are likely to use any legislative vehicle at hand to continue the attack.

The egregious cuts in the House resolution include the elimination of support for Title X, the federal family planning program for low-income women that provides birth control, breast and cervical cancer screenings, and testing for H.I.V. and other sexually transmitted diseases. In the absence of Title X’s preventive care, some women would die. The Guttmacher Institute, a leading authority on reproductive health, says a rise in unintended pregnancies would result in some 400,000 more abortions a year.

An amendment offered by Representative Mike Pence, Republican of Indiana, would bar any financing of Planned Parenthood. A recent sting operation by an anti-abortion group uncovered an errant employee, who was promptly fired. That hardly warrants taking aim at an irreplaceable network of clinics, which uses no federal dollars in providing needed abortion care. It serves one in five American women at some point in her lifetime.
