Rep. Greg Casar (D-TX) announced his reelection campaign Monday amid Texas Republicans’ redistricting efforts, releasing a video highlighting his time as a labor organizer.

The video was launched after the House Progressive Caucus Chairman avoided a possible primary against Rep. Lloyd Doggett (D) under the GOP’s new map. The video was made by Morris Katz, a senior adviser for 33-year-old Zohran Mamdani’s widely successful New York mayoral primary campaign, according to Politico.
