Mitt Romney stepped up his attack on President Barack Obama's health reform program Sunday, accusing the president of "fundamental dishonesty" that has "undermined the foundation of his second term."

The harsh comments from Obama's 2012 rival follow repeated attempts by the Obama administration to liken the current measure, derisively known as "Obamacare," to the health reform law that Romney championed as Massachusetts governor.

"The president failed to learn the lesson that came from the experience of Massachusetts," Romney said on NBC's "Meet the Press." His state's efforts showed the merits of avoiding a "one-size-fits-all plan," Romney said. "States should be able to craft their own plans."
