Washington (CNN) – Republican presidential candidate Jon Huntsman disparaged his GOP rivals and President Obama for not publicly supporting a plan to solve the debt ceiling debate.
Speaking before a group of conservative environmentalists in Washington, D.C. Thursday, the former Utah governor and U.S. ambassador to China said he supports the plan put forward but House Speaker John Boehner.
"The president has not put forward a concrete deal on the table, none of my opponents have supported a plan that would allow us to avoid default," Huntsman said to the Republicans for Environmental Protection. "This is not a time ladies and gentleman to be playing politics."
With America's future at stake, Huntsman stressed the importance of leadership from America's elected officials.
"This is a time when leadership matters and you've got to stand up and voice where you are," Huntsman said. "The president is a good man, but on the most important issue of our time, that of expanding our economy and creating jobs, he has failed us."
Huntsman's jabs are the latest examples of his ramped up campaign rhetoric. He continues to contrast his stance regarding the debt ceiling with those of his opponents, particularly front-runner Mitt Romney, who has yet to outwardly support a plan to end the standoff.
During a campaign stop in Ohio Wednesday, Romney said he will not "comment on the day to day negotiating process."
"My position is very clear, which is I favor a cut, cap and balance program for federal spending," the former Massachusetts governor said.
Huntsman drew on his experience as governor of Utah to explain his solutions for positioning America "back in the game," including tax reform, regulatory reform and energy independence.
"Conservation is conservative," Huntsman said. "I'm not ashamed to be a conservationist. I also believe that science should be driving our discussions on climate change."
