Trump has just endorsed Mitt Romney for senate seat in Utah, the man he called the dumbest and worst candidate in history during the 2016 presidential campaign. Can't the man just make up his mind?

He tweeted ".@MittRomney has announced he is running for the Senate from the wonderful State of Utah. He will make a great Senator and worthy successor to @OrrinHatch, and has my full support and endorsement!"

In 2012 he supported Mitt Romney, tweeting "Make sure you get out and vote...most important election of our generation...go Romney!"

In 2014 he tweeted "I can't believe that Mitt Romney would run for president again. He had his chance and blew it in the last weeks of the race."

In 2016 he tweeted "Mitt Romney, who was one of the dumbest and worst candidates in the history of Republican politics, is now pushing me on tax returns. Dope!" and ".@MittRomney was a disaster candidate who had no guts and choked! Romney is a total joke, and everyone knows it!"

And now he thinks Romney is a great guy and politician again. Go figure.
