Mitt Romney called Donald Trump a "phony, a fraud," and a "con man" in a national speech urging Americans to disavow the GOP front-runner Thursday.
The former GOP presidential nominee called Trump's policy proposals "flimsy, at best," and said he'd trigger a trade war, drive up the deficit and lead the nation into a recession.
"Now, I know you say, 'Isn't he a huge business success, and doesn't he know what he's talking about?' No he isn't, and no he doesn't," Romney said. "His bankruptcies have crushed small businesses and their workers. He inherited his business; he didn't create it."
Trump's foreign policy proposals are "recklessness in the extreme," Romney continued, before turning to a more personal attack.
"Dishonesty is Donald Trump's hallmark," Romney said, pointing to Trump's "bullying, the greed, the showing off, the misogyny, the absurd third-grade theatrics."
"If we Republicans choose Donald Trump as our nominee, the prospects for a safe and prosperous future are greatly diminished."
