"This is a tremendously serious matter that has never happened, to anywhere near this extent, before. The Court will be compromised and demeaned until this very big problem is solved!"
Supreme Court officials have been seeking the source of the leak since Politico posted the draft opinion in May, including taking measures to demand law clerks to supply cellphone records and sign affidavits.

The Supreme Court has voted to repeal the landmark Roe v. Wade ruling, according to a first draft majority opinion written by Justice Samuel Alito.
The draft opinion is a full-throated, courageous repudiation of the 1973 decision which guaranteed federal constitutional protections of abortion rights and a subsequent 1992 decision — Planned Parenthood v.
