McCain who has not talked about immigration as frequently since securing the GOP nomination, took personal responsibility for Congress's failure to enact immigration reform last year
"Senator (Ted) Kennedy and I tried very hard to get immigration reform, a comprehensive plan, through Congress," McCain replied.
He said such reform is crucial to California's agricultural sector as well, which needs a temporary agriculture workers programme.
RockYou founder and CEO Lance Tokuda told McCain that low taxes are vital to the flow of venture capital dollars that make possible companies like his own.
McCain said it is 'indisputable' that reducing capital gains taxes produces higher revenues and the nation also must lower its corporate tax rates which are among the highest in the world.
Among the audience were former governor Pete Wilson, insurance commissioner Steve Poizner, Stanford University president John Hennessy and former Federal Communications Commission chairman Michael Powell.
