The Sixth Circuit Court of Appeals plans to hear a challenge Thursday to a Biden administration rule that forces taxpayers to fund abortion groups, including the billion-dollar abortion chain Planned Parenthood.

Bloomberg Law reports the appeals court will consider a request from 12 states for a preliminary injunction to block the rule regarding Title X, a taxpayer-funded family planning program.

Title X funds are not supposed to be used for abortions. The program provides family planning services to low-income individuals, and the law states that Title X grants may not be used “where abortion is a method of family planning.”

However, Planned Parenthood, the largest abortion provider in the U.S., was one of the largest recipients of Title X grants for years. In 2019, the Trump administration issued a rule ensuring that funding would not be used to support abortions, and Planned Parenthood dropped out of the program.

In 2021, however, the Biden administration issued a new rule that requires Title X recipients to refer for abortions and ends the requirement that abortion facilities separate their abortion practices from their Title X services. Now, Planned Parenthood and other abortion groups are receiving tax dollars through the program again.
