With the confluence of crises confronting Joe Biden's administration — and an evenly divided Senate in which she would deliver the tie-breaking vote — Harris is shaping up to be a central player in addressing everything from the coronavirus pandemic to criminal justice reform.

Symone Sanders, Harris' chief spokeswoman, said that while the vice president-elect's portfolio hasn't been fully defined yet, she has a hand in all aspects of Biden's agenda.

"There are pieces that Biden may specifically ask her to champion, but outside of that she is at the table for everything, involved in everything, and giving input and feedback and being a supportive partner to him on all pieces," she said.
