U.S. President-elect Donald Trump is considering Mitt Romney, the 2012 Republican presidential nominee, for secretary of state, NBC News reported on Thursday, citing unnamed sources.

In March, the former Massachusetts governor called Trump “a phony” and “a fraud” when discussing the then-candidate. Trump, who endorsed Romney in 2012, has called him a loser, adding that Romney begged for his endorsement and “would’ve dropped to his knees” for it. He has also said that he “choked like a dog” during his 2012 presidential campaign against President Barack Obama.

Others reportedly under consideration for the secretary of state position include former New York City Mayor Rudy Giuliani and South Carolina Governor Nikki Haley. Another possibility is Senate Foreign Relations Committee Chairman Bob Corker, who told CNBC on Wednesday he’s “in the mix” for the job.
