Over the past week, former presidential candidate Mitt Romney has become an outspoken antagonist of Republican candidate Donald Trump, blasting Trump's political policies and begging the nation to steer clear of him. On Tuesday night (Mar. 8), Romney brought that argument to… Jimmy Kimmel Live!

Watch above as Romney reads off mean tweets from Trump himself and his social media supporters. The 2012 candidate is a good sport about it all, reading, "'Mitt Romney equals loser' -- that's true, actually. I lost!"

Will Romney's hijinks turn the tide against Trump? Only time will tell. In the meantime, watch Jimmy Fallon combine Trump with Fuller House in a recent sketch.
