President-elect Trump’s nominee for labor secretary, Andy Puzder, has been having second thoughts in recent days about his potential post in the incoming administration. The CEO of the parent company of the Hardee’s and Carl’s Jr. fast-food chains “may be bailing,” according to a Republican source close to the transition team.

“He is not into the pounding he is taking, and the paperwork,” the source told CNN, referring to criticisms from Democrats, labor unions and liberal organizations.
