One day after calling Republican presidential candidate Donald Trump — a phony, a fraud— former GOP presidential candidate Mitt Romney appeared on the ’Today’ show with Matt Lauer.

Friday morning, the ’Today’ show host asked Romney if he thought his Thursday speech at the University of Utah's Hinckley Institute of Politics would make any difference.

"I don't know if it will, or not, but I knew I couldn't stand silent anymore," Romney told Lauer. He also said his actions were prompted in part by imagining what he would tell his grandchildren if they asked what actions he took to stop Trump.

During his speech Thursday, Romney also criticized Trump's "personal qualities, the bullying, the greed, the showing off, the misogyny, the absurd third-grade theatrics."

The New York Times' Patrick Healy and Jonathan Martin took a similar view of Thursday night's Republican presidential debate, saying the debate 'deteriorated into the kind of junior high school taunts that have startled many Republican elders but have done little to dent Mr. Trumps broad appeal.'

During the show Friday, Lauer noted that Romney's criticism of Trump, coming from a former presidential candidate toward a current candidate, is unprecedented. Lauer showed a clip of Romney from four years ago when Trump endorsed his political campaign. In the clip shown, Mitt of 2012 praised Donald Trump's business successes.

"Just because he's made a lot of money doesn't mean his economic policies are good for America," Romney countered Friday.
