Democratic presidential nominee Joe Biden again avoided a question about whether he backs growing calls from his party to expand the Supreme Court following President Trump's nomination of Amy Coney Barrett on Sunday.
Biden has long opposed the issue of court-packing, but Ruth Bader Ginsburg's death has revived the concept of expanding the number of Supreme Court justices in order to shift its ideological balance.
If Republicans confirm Barrett, it would tilt the bench 6-3 in favor of conservatives.
He echoed that sentiment again during a Democratic primary debate in October.
But some Democrats have argued that expanding the nation's high court is necessary.
