Session is scheduled to end at midnight tonight.
Republicans hadn't returned to the chamber as of 9 p.m. Friday night. Democrats hold an upper hand in the process with a 53-47 majority in the chamber. They drew the maps in what is one of the most partisan duties of the Legislature. Lawmakers craft new districts once a decade, trying to ensure their political party will win the most seats and control the legislative process for the next 10 years. Republicans want changes on some of the eight districts they've picked as having the most egregious problems.
