Attorney General Eric Holder can't explain constitutional basis for Obama's executive orders

From the Washington Examiner via Breitbart TV)

Attorney General Eric Holder couldn't explain the constitutional basis for executive orders such as President Obama's delay of the employer mandate because he hasn't read the legal analysis -- or at least, hasn't seen it in a long time.

"I'll be honest with you, I have not seen -- I don't remember looking at or having seen the analysis in some time, so I'm not sure where along the spectrum that would come," Holder replied when Sen. Mike Lee, R-Utah, asked him to explain the nature of Obama's constitutional power to delay the mandate.

Well, first of all, one must assume Holder is NOT being honest and second, shouldn't Holder have asked his boss, the Constitutional Law Lecturer about the constitutional basis for the executive orders?
