Donald Trump Hits Back At 'Choke Artist' Mitt Romney

Republican presidential candidate Donald Trump responded to Mitt Romney's searing broadside on Thursday with one of his favorite put downs in the race for the GOP nomination.

"He's a choke artist," Trump said at a rally in Portland, Maine, referring to the former GOP presidential nominee's failure to defeat President Barack Obama in 2012. "We cannot take another loss. Mitt is indeed a choke artist."
