Just hours after Mitt Romney held an exclusive speech dedicated towards attacking Donald Trump, he fired back by attacking Romney's inability to defeat Barack Obama in 2012.
"He was a failed candidate, he should have beaten President Obama very easy," Trump said. "He failed miserably and it was an embarrassment to everybody including the Republican Party."
"I guess, obviously he wants to be relevant, he wants to be back in the game."
Trump went on the discuss free trade and the effects it has on the United States.
