With Wednesday’s decision by Andrew Puzder to withdraw his nomination as labor secretary, attention turned to President Donald Trump’s possible replacements.

Bloomberg said the names being floated include Catherine Templeton, Joseph Guzman, Peter Kirsanow and Alexander Acosta.

Puzder, the CEO of the company that owns the Hardee's and Carl's Jr. fast food chains, decided to step aside as Republicans refused to line up behind him in advance of his scheduled confirmation hearing. Senate GOP leaders told the White House four and as many as 12 lawmakers were refusing to back the nominee because of concerns over his decision to pay some employees in cash, his hiring of an undocumented worker and his comments about the American workforce.

"After careful consideration and discussions with my family, I am withdrawing my nomination for secretary of labor," Puzder said in a statement. "I am honored to have been considered by President Donald Trump to lead the Department of Labor and put America's workers and businesses back on a path to sustainable prosperity.

Templeton formerly headed the South Carolina health department under then-Gov. Nikki Haley, whom Trump selected as his U.N. ambassador, and earlier was director of the state Department of Labor, Licensing and Regulation. The Charleston Post and Courier reported in November Templeton was considering a run for governor in 2018 but she decided to postpone any announcement last month. Templeton opposes unions and never has held elective office. She met with Trump in December.
