The Senate is considering a bill that would eliminate the filibuster, or limit the number of votes a senator can garner in the chamber.
The move would be the first step in a broader overhaul of the Senate.

Sanders has made the filibuster a key issue of his 2016 presidential campaign, and he was among the first to introduce the proposal in the fall of 2016.
It has been a sticking point for Republicans in the past, particularly after the Supreme
