Texas Gov. Greg Abbott says that Planned Parenthood has “very serious legal issues” in Texas.

A letter was sent to Planned Parenthood affiliates in Texas on Monday notifying them that their Medicaid contracts will be terminated.

Abbott defended the state’s decision to cut off Medicaid funding to Planned Parenthood clinics, “money that they do not deserve,” on Fox News’ “America’s Newsroom” and says he expects and hopes for a legal challenge.

“I want to put these Planned Parenthood officials under oath and get them to swear about the practices that they were conducting in the state of Texas,” Abbott told Fox News’ Bill Hemmer. “Either their horrific practices will be revealed or they may be found in violation of law for perjury.”

Abbott says Texas would have cut Medicaid funding for Planned Parenthood with or without the string of undercover videos released by the Center for Medical Progress, which have given rise to questions about whether Planned Parenthood has made a profit from selling aborted babies’ body parts. Planned Parenthood has criticized the videos’ editing and denied any illegal activity.
