Democratic presidential contender Hillary Rodham Clinton promised on Wednesday to help small businesses, saying U.S. tax rules were skewed in favor of big corporations and made it time-consuming and costly for small employers to navigate the tax code.

On the second day of her campaign rollout in Iowa, which holds the first nominating contest in early 2016, Clinton told small business owners she wanted to make it easier for them to get loans and cut through regulatory red tape.

"I want my campaign to figure out how we're going to jump-start small businesses," she said at a roundtable with small business owners held at a family-owned fruit distributor in Norwalk, Iowa, just outside Des Moines.
