Why This Matters: Project 535

Illinois has 19 members of Congress who are part of the 535 total members (100 senators + 435 representatives) that Project 535 aims to replace with servant leaders.

Every single one of these 19 positions represents an opportunity for a servant leader to step forward and serve the people of Illinois with integrity, transparency, and accountability.
