On Sunday Mitt Romney told Jake Tapper he does not believe Donald Trump will be the Republican nominee for president. Later in the day Donald Trump responded.

Newsmax reported:

Republican presidential front-runner Donald Trump said Sunday he isn’t interested in criticism from the party’s 2012 nominee.

Mitt Romney, the 2012 challenger to President Barack Obama, said on CNN’s “State of the Union” that he doesn’t believe Trump will end up being the party’s nominee.

Pressed by host Jake Tapper on whether he would vote for Trump should he end up winning the nomination, Romney replied, “I would vote for the nominee of the Republican party, and I don’t believe that’s going to be Donald Trump.”

Trump responded with a series of tweets afterward, criticizing Romney’s loss to President Barack Obama in an election Trump says he should have won.
