Romney to slam Trump as 'a phony, a fraud'

Former Republican presidential nominee Mitt Romney will slam current GOP front-runner Donald TrumpDonald John TrumpKoch-backed group launches six-figure ad buy against Heitkamp Anti-abortion Dem wins primary fight Lipinski holds slim lead in tough Illinois primary fight MORE as "a phony, a fraud" during remarks on Thursday, according to multiple reports.

Romney will reportedly call on voters to "make the right choices" during a speech at the University of Utah that comes a little more than a week before the final major round of voting in the GOP race on March 15.

"Donald Trump is a phony, a fraud," Mitt Romney will tell voters. "His promises are as worthless as a degree from Trump University. He’s playing the American public for suckers: He gets a free ride to the White House and all we get is a lousy hat."

Some have suggested that Republicans need a major address to frame the decision before voters as historic in nature, invoking Reagan's "time for choosing" speech, which appears to be what Romney will attempt to do.

Excerpts of his speech show that Romney will say America faces "another time for choosing," hearkening back to Reagan's 1964 address, adding that the election could have "profound consequences" for Republicans and the country.

"Donald Trump says he admires Vladimir Putin, while has called George W. Bush a liar," Romney plans to tell his audience, according to excerpts. "That is a twisted example of evil trumping good."
