Mitt Romney Speech On Donald Trump Mocked By Stephen Colbert On ‘The Late Show’ [VIDEO]

The last time businessman Mitt Romney was at the center of Republican presidential politics — as the 2012 nominee — comedian Stephen Colbert was still hosting "The Colbert Report" on Comedy Central. Colbert has a new show now, but he is still giving Romney a hard time.

On CBS' "The Late Show with Stephen Colbert" Thursday, Colbert took some shots at Romney, after the former presidential candidate gave a speech in Utah denouncing 2016 Republican front-runner Donald Trump and laying out a plan to halt his path to the nomination via a brokered convention.

“They broke the seal on Mitt’s hyperbolic dignity chamber,” Colbert joked. “And he shambled out and brought the pain.”

Colbert played a clip from Romney's speech, in which Romney critiques Trump's shortcomings as a businessman, pointing out some of his more well-known failures — Trump University, Trump Magazine, Trump Vodka, etc. Colbert said there was some hypocrisy in that criticism.

“True, Trump has put his name on some terrible investments," said Colbert. "For example, four years ago, he endorsed Mitt Romney for president.”

The comedian went on to mock the strategy of rolling out a failed 2012 candidate to attack the current party front-runner. Colbert sarcastically urged Romney to launch a campaign to secure the nomination through a brokered convention, pulling out outdated memorabilia he claimed he saved from 2012, including a Jeremy Lin "Linsanity" shirt.

While Romney may not be a candidate, he pulled no punches going after Trump Thursday.

"His is not the temperament of a stable, thoughtful leader," Romney said in his speech, calling Trump "a phony" who is "playing the American public for suckers."

All the same, Donald Trump appears to be presumptive Republican nominee after key wins in the states of Alabama, Arkansas, Georgia, Tennessee, Massachusetts and Virginia in the Super Tuesday primaries. Trump currently holds 319 delegates. Sen. Ted Cruz is a distant second with 226 delegates, and establishment favorite Sen. Marco Rubio of Florida trails even further behind with 110 delegates. 1,237 delegates are needed to lock up the nomination.

Trump's Republican rivals may now be exploring a strategy to drag out the primary process and unseat Trump in a brokered convention.
