The Congressional Progressive Caucus PAC announced Tuesday its support of Evanston Mayor Daniel Biss in his bid for Congress in the 9th Congressional District.

Biss is the seventh congressional candidate the PAC has announced support for this cycle, including State Sen. Robert Peters, who’s running for Congress in the 2nd District, and Rep. Adelita Grijalva, the newest member of Congress from Arizona, who was sworn into Congress earlier this month.

“In his decades of service to Illinois as an educator, activist, legislator and as a mayor, Daniel Biss has been a bold progressive change agent and a critical ally for working families,” caucus co-chairs  Rep. Pramila Jayapal of California and Rep. Maxwell Frost of Florida said in a statement.

The Progressive Caucus includes 94 Democratic members of the House of Representatives and one senator, Vermont Sen. Bernie Sanders.

“With our democracy facing an unprecedented assault from Donald Trump and his MAGA cronies, the Congressional Progressive Caucus is leading the fight to put our government back on the side of the people,” Biss said in a statement. “We need the bold leadership of the CPC in Congress to unrig our economy, make healthcare more accessible, protect our environment and fix our corrupt political system.”

Incumbent Rep. Jan Schakowsky of Evanston, who’s yet to endorse any candidate in the crowded Democratic congressional primary to replace her, is a member of the Progressive Caucus but not a member of the PAC’s board, which is made up of seven House Democrats, including two Illinois representatives — Rep. Delia Ramirez (3rd) and Rep. Chuy García (4th).

The PAC is co-chaired by Reps. Pramila Jayapal of California, Greg Casar of Texas and Maxwell Frost of Florida.

In a statement on social media, the PCP called Biss a “critical partner in advancing bold progressive priorities” and noted his “deep roots in the district and decades of service to Illinois.”

“He will be a strong partner in moving forward critical legislation, including Medicare for All, the PRO Act, a wealth tax on billionaires and ultra millionaires, as well as holding ICE accountable and ensuring humane reforms to our immigration system,” Jayapal and Frost wrote. “We are proud to endorse him.”

Biss currently leads in most polls in a field of over a dozen Democrats to succeed Schakowsky. Other candidates that stand out from the pack include social media content creator Kat Abughazaleh, State Sen. Laura Fine, State Sen. Mike Simmons, State Rep. Hoan Huynh and Skokie School Board member Bushra Amiwala.

The primary election is on Mach 17, 2026.
