A group of 56 lawmakers led by Rep. Vicky Hartzler, R-Mo., is urging federal officials to investigate the extent to which Planned Parenthood fails to report suspected sexual abuse of minors.

In a letter Thursday to the Department of Health and Human Services, Hartzler and 55 other Republicans ask the agency to probe whether Planned Parenthood, as a recipient of federal Title X funds, “failed in its duty to report suspected child abuse to local authorities and to HHS.”

Hartzler and other signers announced the formal request of an investigation in a press conference Thursday morning at the Capitol.

Their letter to HHS Secretary Alex Azar comes less than a week after the pro-life group Live Action released a report alleging Planned Parenthood, the nation’s largest abortion provider, covered up evidence of child sexual abuse.

Among the signers are two senators—Joni Ernst of Iowa and James Lankford of Oklahoma. Besides Hartzler, the 53 members of the House requesting the probe include Chris Smith of New Jersey, Mark Walker of North Carolina, and Diane Black of Tennessee.

The Daily Signal previously reported that the Live Action study, “Aiding Abusers: Planned Parenthood’s Cover-Up of Child Sexual Abuse,” alleges that Planned Parenthood has been caught on multiple occasions providing abortions to victims of sexual abuse as young as 12 and 13, failing to report suspected sexual abuse to authorities, and sending victims back to their abusers.

Conservative lawmakers have sought unsuccessfully to end taxpayer funding of Planned Parenthood. The abortion giant, which received a total of $543.7 million in taxpayer dollars in 2016, contends that none of that money goes toward abortions.
