After five fulfilling weeks of connecting with constituents during the August District Work Period, I returned to Capitol Hill today. Throughout my weeks in the East Bay, I met with small business owners, spoke with first responders, visited local nonprofits, delivered federal funding checks for important projects in our district, and connected with countless constituents across our community.
