The White House has enlisted former budget official Jeffrey Zients to help fix the online enrollment process under the Affordable Care Act, White House press secretary Jay Carney confirmed Tuesday.

Carney said Zients, who is slated to take over the helm of the White House National Economic Council, would take on a "short term assignment: at the Department of Health and Human Services.

"He’s an expert in the field of effective management," Carney said, adding the agency would be "tapping his experience and expertise."
