[UPDATE] Biden in Iowa: Romney's Swiss Bank Account 'Out of Touch' with American Middle Class

Vice President Joe Biden called GOP presidential candidate Mitt Romney, "a good, decent man," at a campaign stop in Waterloo on Tuesday, but said the Republican is out of touch with the American middle class.

"A prospective president with a Swiss bank account and a retirement account in the Cayman Islands? Did you ever think the nominee of a major political party running for President would have a Swiss bank account?" he said. "Talk about out of touch."

Biden railed against the Republican candidate's past at Bain Capitol, saying Romney outsourced jobs. He said he also outsourced state contract jobs during his time as governor.

Kym Salow, 47, of Independence, said she believes such volunteer outreach efforts are vital.
