The debate, sponsored by KPCC-FM, Pasadena, Calif., and the La Opinion newspaper, was the second and final one between the two rivals, the Los Angeles Times reported. Boxer, remaining in Washington because the Senate was still in session, was at a microphone at an NPR station in the nation's capital.
Both women were in attack mode.
Fiorina called Boxer, who is seeking a fourth term in the Senate, a big spender. She said Boxer has done nothing for California's Central Valley, hit hard by drought.
"Washington has a spending problem, and we need to hold our representatives accountable," Fiorina said. "Barbara Boxer in her 28 years in Washington, D.C., has done nothing to curb spending."
Boxer said Fiorina as chief executive of Hewlett-Packard had cost U.S. workers their jobs.
