Democratic state Representative Nicole Collier hunkered down for a second night in the Texas Capitol building rather than accept a mandatory police escort in a redistricting battle as President Donald Trump seeks to keep Republican control of Congress.

Texas’ Republican-led legislature gave initial approval to a controversial new electoral map on Wednesday, a redistricting move designed to give the GOP an additional five seats in the U.S.

A handful of Texas House Democrats were locked in the state Capitol overnight as a protest against a House rule that required members who fled the state earlier this month to be followed by a police chaperone.
