Supreme Court justices privately said the abortion leak locked in their votes on overturning Roe v. Wade: report

• Supreme Court justices privately revealed the leak locked their votes in on the abortion case.
• That's according to CNN Joan Biskupic's reporting in her forthcoming book.
• The court voted 5-4 to overturn Roe v. Wade last June. 

Last spring's unprecedented leak of a draft opinion that showed the Supreme Court was ready to overturn federal abortion rights ended up locking the justices' votes in place.
