She is pissed and rightfully so.

Context: A filibuster is a Senate rule that allows a minority of senators to delay or block a vote on a bill by extending debate indefinitely. To break a filibuster and proceed to a vote, the Senate needs 60 votes out of 100 instead of a simple majority of 51.

She’s essentially calling them out on their hypocrisy. It only ever stops progressive policies, never Republican ones.
