Mitt Romney said the health care reform mandate constitutes a “tax” Wednesday, contradicting the way a senior adviser to his campaign characterized his position earlier this week.

“Supreme Court is the final word, right?” Romney told CNN Senior Congressional Correspondent Dana Bash and CNN Producer Shawna Shepherd. “The highest court in the land? They said it’s a tax didn’t they?

“So it’s a tax, of course, if that’s what they say it is,” he continued.

Romney had first commented on the matter in a CBS News interview Wednesday.

The high court last Thursday upheld the individual mandate provision of the law under Congress’ taxation power.
