President-elect Trump spoke with several of his Republican rivals over the weekend and spent Sunday morning gloating about his "very nice" conversations with them.

Trump spoke with 2012 GOP nominee Mitt Romney, a vehement critic of his throughout the election cycle, and ex-White House hopefuls John Kasich, Carly Fiorina and Jeb Bush, according to social media and pool reports.

"Mitt Romney called to congratulate me on the win. Very nice!" the president-elect tweeted shortly after he and Romney spoke.

"Jeb Bush, George W [Bush] and George H.W. [Bush] all called to express their best wishes on the win," Trump added in a separate tweet.

"Governor John Kasich of the GREAT, GREAT, GREAT State of Ohio called to congratulate me on the win. The people of Ohio were incredible!" he wrote.

Kasich, Romney and the Bushes all declined to vote for Trump in last Tuesday's election and routinely criticized the incoming Republican president and many of his policy proposals during the election. They also boycotted the GOP convention in July in protest of their party's nominee.

Trump's campaign manager, Kellyanne Conway, told reporters Sunday morning that the president-elect was "very busy ... meeting with different people and receiving many different phone calls" from his primary opponents.

"They had a very productive call and Gov. Bush was extremely gracious congratulating Mr. Trump on his victory and wishing him well as our next president," Conway said of Jeb Bush.
