Protesters are chanting outside the room where Indiana state Senators are expected to take a final and deciding vote on redistricting Thursday.

Even in the face of pressure from the White House and about a dozen threats made against Indiana lawmakers, many state senators in the Republican supermajority are outright opposed to the legislation or hesitant to take a stance. Going into the vote Thursday, it is unknown if the legislation has the support needed to pass.

Protesters are chanting "Vote no!" and "Fair maps now."

The proposed congressional map is designed to deliver all nine of Indiana's congressional districts to the GOP. Republicans currently hold seven of those seats.
