Redistricting is one of 18 items on the agenda during the Texas legislative special session that begins July 21.

Texas Republicans are signaling a possible redrawing of the state's congressional map in a move that's likely to spark legal battles and deepen partisan divides. Gov. Greg Abbott on Wednesday called for legislation to revise Texas' districts—maps that are tied up in federal court under claims they discriminate against Black and Latino voters.

The state legislature will take the rare step of considering a mid-decade redrawing of district lines in light of concerns raised by the Justice Department.
