Trump tweets about Romney’s run for Senate – and Mitt responds

President Donald Trump tweeted about the announcement from Mitt Romney, once his greatest critic, that he would be running for the U.S. Senate seat in the state of Utah.

Here's what he tweeted:

"[Mitt Romney] has announced he is running for the Senate from the wonderful State of Utah.

"He will make a great Senator and worthy successor to [Senator Orrin Hatch]," he added, "and has my full support and endorsement!"

Romney responded and thanked him for his endorsement.

"Thank you Mr. President for the support," he tweeted. "I hope that over the course of the campaign I also earn the support and endorsement of the people of Utah."

"Choked like a dog!"

Trump was very critical of Romney in the primary election in 2016, as the former presidential candidate assailed him for not reflecting the conservative values Romney believed the Republican Party stood for.

Trump hit him back hard, especially from his Twitter account:

Many expect that Romney could become one of Trump's biggest critics again, this time from a likely seat in the U.S. Senate.

Polling shows Romney has as much as an overwhelming 50-point advantage over his Democratic opponent, Jenny Wilson.
