Lawmakers demand Romney release tax returns

NATIONAL -- There is mounting demands from Republicans and Democrats for former Massachusetts governor and presumptive Republican presidential candidate Mitt Romney to release his tax returns.

At the heart of the question is Romney's private equity firm he started outsource job.

Romney insisted he'll only release two years worth of tax returns.

Some Republicans say he should just release the returns.

"The advice I would give Romney is 'who cares about your tax returns?' Release them. We need this campaign to be about Obama's record," Haley Barbour, former Republican governor of Mississippi, said.

Romney held his first campaign rally in a week. And wasted no time in attacking President Obama on the economy.
