Democratic presidential candidates asked if they would pack the Supreme Court

The top 2020 Democratic presidential contenders were asked at Tuesday's debate about expanding the Supreme Court, in a concept commonly referred to as "court packing." Zoe Tillman, a legal reporter for BuzzFeed News, spoke to CBSN's "Red & Blue" about the candidates reponses and the battle within the Democratic Party to make the courts a top issue in 2020.
