President Obama has yet to make good on the administration's promises that he would sign up for health insurance on the new government exchanges, the White House acknowledged on Monday.

White House press secretary Jay Carney said that Obama has not signed up for Obamacare and that he did have a reason for the delay.

A reporter pressed Carney on whether the White House would make it an open-press event if and when Obama does enroll.

“I'll get back to you,” Carney replied.

Shortly after Obama signed the new health care law in March 2010, a White House official said the president planned to walk the walk and sign up for the insurance exchanges his law created.

“The president will participate in the exchange,” an administration official told USA Today at the time.

If he follows through with the pledge, Obama will be opting to pay for the insurance without receiving a taxpayer subsidy because the law doesn't provide the tax benefit for those with access to generous coverage through their employers.

The gesture also will be largely symbolic because presidents and their families have several layers of health protection. They have access to a White House Medical Unit, a section of the White House Military Office responsible for the medical needs of the president, the vice president, their families, as well as White House staff and visitors while they are working on White House grounds.

Obama also has access to the official physician to the president, who has served every commander-in-chief since George Washington.
