Tim Pawlenty on Monday trod carefully when commenting on Mitt Romney's healthcare reform law just one day after he tied the plan to President Obama's healthcare law, calling it "ObamneyCare."

Pawlenty, the former Minnesota governor, declined to take further shots at Romney while the two stood together onstage at the GOP presidential primary debate. He explained that he was simply citing President Obama's own words when he came up with the term "ObamneyCare."
