Costa is a product of Fresno County schools, an alumnus of San Joaquin Memorial High School and California State University, Fresno.

As a member of Congress, Costa has applied his farming background to fighting for water, agriculture, healthcare, and the economy. In these capacities, he has protected California agriculture, enhanced water storage, repaired critical infrastructure, and advocated for a strong national defense to keep us safe from threats here at home and abroad. His efforts in Congress have been recognized by organizations like the American Farm Bureau Federation, the U.S. Chamber of Commerce, and the National Organization for Victim Assistance. Costa is committed to building a stronger nation for our children and protecting the future of our democracy for generations to come.
