The White House on Wednesday called the latest delay of the Obamacare employer mandate a “common-sense approach” to appease certain businesses worried about implementation of the Affordable Care Act.

The administration has been on the defensive this week after the Treasury Department gave companies employing between 50 and 99 workers until 2016 to provide health insurance for their employees or pay a fine.

“This is a common-sense approach to phasing an aspect of the law … for some employers,” White House press secretary Jay Carney said.

“We're talking about 2 percent of employers,” he added.

Republicans have hammered the White House for unilaterally delaying a series of key Obamacare provisions, saying that President Obama is overstepping his authority by ignoring the legislative process.

Carney also dismissed an op-ed in the Washington Post Wednesday that accused the president of employing an “increasingly cavalier approach to picking and choosing how to enforce” Obamacare, saying the administration was merely granting flexibility to a small portion of businesses affected by the law.
