Biden criticized the Supreme Court as "more of an advocacy group."
The court overturned Roe v. Wade in June.
"The Supreme Court is more of an advocacy group these days than it is ... evenhanded," the president continued.
Biden has publicly criticized the Supreme Court since June, when a 5-4 conservative majority overturned Roe v. Wade, the landmark ruling that established the constitutional right to abortion nearly 50 years ago.
"The president believes the Supreme Court must be nonpartisan," Jean-Pierre said, "and committed to upholding the Constitution and the rule of law regardless of politics."
