Fast-food chief executive Andrew Puzder’s nomination to lead the U.S. Labor Department is inching forward amid opposition from U.S. Senate Democrats and employee advocates who contend his confirmation would imperil Obama administration regulations.

Puzder, chief executive officer of CKE Restaurants, is set to appear Feb. 2 in the U.S. Senate Committee on Health, Education, Labor and Pensions. Committee chairman Sen. Lamar Alexander, R-Tennessee, on Monday called Puzder “a respected Tennessee business leader who understands how excessive regulation can destroy jobs.”
