Serving as Deputy to Secretaries Ray LaHood and Anthony Foxx, Porcari was instrumental in implementing Department programs, including over $3 billion in Transportation Investment Generating Economic Recovery (TIGER) grants (originating from the American Recovery and Reinvestment Act of 2009) and USDOT's stringent Buy America Act provisions, in place to ensure transportation projects are built by American workers using domestic materials. In addition to serving as operations officer over USDOT's more than 55,000 employees, Deputy Secretary Porcari oversaw resolution on an array of programs and issues, including the vehicle return/rebate program Cash-for-Clunkers, Toyota's recall of 2.3 million vehicles due to unexpected acceleration, and implementation of the Congressional transportation legislation Moving Ahead for Progress in the 21st Century (MAP-21).
