Amid mounting opposition from Democrats and labor groups, the confirmation hearing for labor secretary nominee and fast-food chief executive Andrew Puzder has been delayed a fourth time. A new hearing date will not be set until the Senate receives key paperwork laying out Puzder’s financial disclosures and detailing his plan for avoiding future conflicts of interest, according to an aide for Sen. Lamar Alexander , the chairman of the Senate Committee on Health, Education, Labor and Pensions.
