CHICAGO – Mayor Brandon Johnson announces the additions of Dominique Warren as the Director of Federal Affairs for the City of Chicago and Santiago Ginebra Campillo as Senior Legislative Assistant of Federal Affairs. These high-impact additions will significantly elevate Chicago's federal affairs operations, fortifying the city's advocacy capabilities in the nation's capital.

“Dominique Warren and Santiago Campillo are exemplary leaders whose expertise working at the highest levels of government will be game-changing assets for Chicago,” said Mayor Brandon Johnson. “These additions are critical in assembling a world-class federal affairs team dedicated to vigorously championing Chicago's priorities in Washington. I am confident their work will ensure our city's voice is heard loud and clear on the national stage and deliver transformative results for our communities.”

Warren brings a wealth of experience and knowledge to his new role. As the former National Deputy Director of Government Relations at the Service Employees International Union, he led federal policy on climate/environmental justice, immigration, and economic policy and coordinated electoral campaigns for Service Employees International Union (SEIU). He liaised with the White House, the Department of Treasury, Commerce, and other federal agencies. In 2010, Dominique served as a mayoral fellow under the Richard M. Daley Administration. Dominique graduated from Morehouse College and attended the Gerald R. Ford School of Public Policy at the University of Michigan.

“I am honored that Mayor Johnson has placed his trust in me to lead Chicago's federal engagement strategy during this pivotal time,” said Dominique Warren. “Having witnessed firsthand the complexities of the federal landscape, I am thrilled to bring my talents back to City Hall to forge strategic partnerships and translate the administration's bold vision into concrete policies and resources that create lasting, equitable impact for our city's residents.” 

Campillo brings extensive experience in government relations and public policy to his new role. In his previous role as a Legislative Counsel in the Mexican Senate, he advised a former presidential candidate on key issues like children's rights, public safety, foreign affairs, and the economy. Campillo has worked with prominent international organizations, including UNICEF, the U.S. Department of Labor, the World Bank, and Save the Children, adding to his extensive experience in legislative advocacy, facilitating major policy reforms, and building strategic partnerships across government and non-profit sectors. He holds a Master of Public Policy from University of Chicago Harris School of Public Policy, a Master of Government and Public policy from Universidad Panamericana and Syracuse University, and bachelor's in public administration and government from Universidad Anáhuac. 

With their combined decades of government relations expertise, including prior roles leading federal policy, Warren and Campillo are uniquely positioned to maximize federal resources and shape policies aligned with Chicago's vision for equitable growth, robust infrastructure investment, and forward-looking climate resiliency.
