Gov. Steve Sisolak has joined nine Democratic counterparts on a letter opposing the Trump administration’s new rule on Title X federal funds that support family planning activities.

The final rule, known as the “gag rule” and approved on Friday, would prevent groups that provide abortions or refer people to abortion providers from receiving funds from the nearly 50-year-old grant program. The program affects groups like Planned Parenthood, which says it would be forced into the “impossible position” of withholding certain information from patients or forgoing funding.

The governors said the rule “would impose sweeping new restrictions on healthcare providers nationwide, prohibiting them from providing comprehensive, medically accurate information to their patients. These politically motivated restrictions threaten access to reproductive healthcare for millions of vulnerable women and men.”

Title X-funded programs served nearly 11,000 people in Nevada in 2017 — most of them low-income and underinsured, according to Planned Parenthood, which is not one of the Nevada recipients receiving the funds but is outspoken about the rule. The group also decried “physical separation” requirements that require separate entrances and exits for facilities receiving Title X funding and those that provide abortion services.

Sisolak and the other governors raised the possibility of legal action if the rule stands.

“We strongly urge you to rescind this rule,” the governors wrote. “Should you choose to move forward with this policy, we will do what is necessary to protect the health of our constituents and explore all possible avenues, including legal options, to block it from being implemented.”
