US Supreme Court law clerks could be asked to turn over their cellphone records as part of the escalating hunt for whoever leaked Justice Samuel Alito’s draft opinion that would overturn Roe v. Wade, a new report revealed Tuesday.

Officials tasked with unmasking the leaker have taken steps to require the clerks to hand over the records and sign affidavits, CNN claimed, citing three unnamed sources familiar with the probe.

These unprecedented developments have prompted some of the clerks to consider retaining their own lawyers.

The latest efforts to get to the bottom of the leak come less than a month after Politico published the draft opinion signaling the conservative-dominated court’s intent to roll back abortion rights recognized nearly 50 years ago.

The bombshell revelation sparked pro-choice protests around the country and triggered legislatures in many red states to pass stricter laws limiting a woman’s right to terminate a pregnancy.

People associated with the nation’s highest court have described the leak as an unprecedented breach of trust.
