Sen. Mike Lee, R-Utah, on Sunday slammed President Obama for a series of unilateral Obamacare delays, saying the White House was openly flouting the Constitution.

“The president knows this is wrong and it's not defensible,” Lee, the Tea Party lawmaker, told “Fox News Sunday.”

Lee said that under Obama’s interpretation of his powers, there is “almost no limit to his authority” and he can act like a “super executive and super legislator.”

The Obama administration recently delayed until 2016 the employer mandate for businesses with between 50 and 99 workers.

It’s the second time the White House has delayed the employer mandate and comes after unilateral extensions of the cap on out-of-pocket medical costs, due dates for Obamacare payments and other key provisions of the president’s signature domestic achievement.

Rep. Xavier Becerra, D-Calif., countered on the Fox program that Obama was simply using the same tools at the disposal of previous presidents.

“The president is providing small businesses with the flexibility they need,” he insisted. “He's using the same authority all presidents have.”

Lee, however, was unmoved by that argument.

“The fact that other presidents may have done it in the past,” the Utah lawmaker said, “doesn’t justify it now.”
