(Bloomberg) — President Donald Trump's nominee to lead the Labor Department, fast-food restaurant executive Andy Puzder, said he employed an undocumented immigrant as a housekeeper until learning of the worker's immigration status — the second Trump nominee to make such a disclosure.

Immigration issues with household employees have forced other presidents' nominees to drop out of consideration, but neither Puzder, the CEO of CKE Restaurants Inc., the parent company of Hardee's and Carl's Jr., nor the chairman of the committee considering his nomination see it derailing the process.

"My wife and I employed a housekeeper for a few years, during which I was unaware that she was not legally permitted to work in the U.S.," Puzder said in a statement released late Monday. "When I learned of her status, we immediately ended her employment and offered her assistance in getting legal status. We have fully paid back taxes to the IRS and the State of California and submitted all required paperwork regarding her employment."
