President-elect Donald Trump is considering Mitt Romney for the position of secretary of state, according to sources who spoke to NBC News.
CNN reported earlier that Romney has a meeting with Trump this weekend to talk about "governing moving forward" and a possible Cabinet position.
Romney is one of several people whom Trump is considering as secretary of state, along with former New York City Mayor Rudy Giuliani, former US Ambassador to the UN John Bolton, and South Carolina Gov. Nikki Haley.
Romney, the former Massachusetts governor, ran for president in 2012, but lost to President Barack Obama. Ever since, Romney and Trump have sparred publicly.

Romney was one of Trump's most vehement critics during the Republican primary, speaking out against him frequently and refusing to give him an endorsement despite the fact that Trump endorsed Romney in 2012. Romney declined to say who he voted for in the general election.
In March, Romney delivered a speech calling Trump a "phony," "fraud," "con man," and "fake." He also said in May that it's "disqualifying for a modern-day presidential nominee to refuse to release tax returns to the voters." Trump has yet to release his tax returns, saying he will do so after a "routine audit" is complete.
Trump, in turn, torched Romney, calling him a "spoiled brat" and "nasty guy."
Romney's spokesperson did not immediately respond to a request for comment.
