Rep. Darrell Issa (R-Calif.) $448.1 million
Issa secured $815,000 in earmarks between 2007 and 2009 to widen a road less than a mile from a medical building in Vista, Calif., that Issa purchased for $16.6 million in 2008. Issa sold the property on Jan. 19 for $15 million. These earmarks were first reported in March by the Center for American Progress and in August by The New York Times. "Rep. Issa's request for the widening project was made on behalf of local leaders and predated his purchase of the medical center building," a spokesman said. –Washington Post
