Austin, Texas - Just hours before he is set to rally with Senator Elizabeth Warren in Austin, Texas progressive Greg Casar got another big boost in his run for Congress.

Massachusetts Rep. Ayanna Pressley on Wednesday announced that she is officially endorsing Greg Casar for Congress for Texas’ 35th Congressional District.

"Greg and I share roots on our respective City Councils, where we’ve been grounded in the importance of close connection to community and centering those closest to the pain," Pressley said.

"On the Austin City Council, Greg has translated his roots as a community organizer into bold, activist leadership to ensure a living wage, fight for survivors of sexual violence, deliver housing justice, immigration justice, and more," she continued.

"I know he’ll bring that same commitment and progressive vision to Congress, and I’m proud to endorse his campaign."

Pressley has joined an impressive list of lawmakers who have thrown their weight behind the Texas-35 candidate, including Sens. Bernie Sanders and Elizabeth Warren as well as Reps. AOC, Jamaal Bowman, Pramila Jayapal, Mondaire Jones, Sheila Jackson Lee, and Sylvia Garcia.

"Texas working families need a representative who will show up and fight for them – someone who will work to pass Medicare for All, stand up to corporate special interests, protect reproductive rights, and fix our grid," Casar said in response to Pressley's endorsement. "I’m honored to have the endorsement of Rep. Ayanna Pressley, who knows how both local and federal leaders can get things done by working with our communities. I look forward to working with her to deliver for TX-35 residents."

The Texas primaries are set for March 1. Early voting is already underway.
