Two Democrats have joined more than 100 Republican members of Congress to protest a proposed rule from the Obama administration prohibiting states from cutting certain taxpayer funds to Planned Parenthood.

The administration raised the ire of conservatives last month when it proposed a rule that states must award Title X family planning dollars based on a provider’s ability to offer quality reproductive services and not whether it offers abortions. The rule appeared aimed at more than a dozen GOP-led states that have taken action over the last year to ban Planned Parenthood clinics from getting Title X funds.
