There is no constitutional requirement to fund Planned Parenthood or even to allow Medicaid to reimburse Planned Parenthood!
More than that, it is patently UNCONSTITUTIONAL for the feds to even be involved in abortion AT ALL. They have no constitutional authority whatever to interfere with state anti-abortion laws.
The feds are outlaws. Period.
You have it backwards: There is NO Constitutional authority for Congress to give penny ONE to PP, let alone for Medi-XYZ...
