Mitt Romney in Utah in March. REUTERS/Jim Urquhart 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.

Trump's campaign manager, Kellyanne Conway, confirmed that the transition team is "working on" setting up a meeting with Romney.

Sen. Jeff Sessions of Alabama said Thursday that he thinks it's good Trump is meeting with Romney.

"There are a lot of talented people that he needs good relationships with," he told reporters. "And I think Mr Romney would be quite capable of doing a number of things. But he will be one of those, I am sure, that's reviewed. Donald Trump will make that decision."

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 endorse him despite Trump endorsing Romney in 2012. Romney declined to say who he voted for in the general election.

After the election, Romney said on Twitter he wished Trump the best.

"Best wishes for our duly elected president: May his victory speech be his guide and preserving the Republic his aim," he wrote.

On Sunday, Trump said Romney called to congratulate him on his victory. Trump said the gesture was "very nice!"

During the primary, however, Romney and Trump didn't have many nice things to say about each other.

Last year, Romney called Trump's campaign rhetoric "problematic," and he continued his criticism of the Republican nominee through the primaries and 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 would do so after a "routine audit" is complete.

Trump also torched Romney, calling him a "spoiled brat" and "nasty guy."

Romney's spokesperson did not immediately respond to a request for comment.
