Joe Biden, who for weeks has declined to clarify his position on progressive activists’ calls to expand the Supreme Court to add liberal justices, has said in a new interview that, if elected, he would establish a bipartisan commission of scholars to study possible ways to overhaul the judicial branch.

"I will ask them to, over 180 days, come back to me with recommendations as to how to reform the court system, because it’s getting out of whack,” Biden, the Democratic presidential nominee, told CBS News’ Norah O’Donnell, according to an interview excerpt made public Thursday and expected to be broadcast in full Sunday on "60 Minutes.”

While Biden opposed court packing during the primaries, he has equivocated since the matter took on new urgency after Justice Ruth Bader Ginsburg died last month and Republicans rushed to fill her seat amid the election endgame — an approach that has allowed the issue to fester and created fodder for a new and sustained line of attack from the right.
