Really? And precisely how would he do that ?
My understanding is that waivers and exceptions are built into the ACA, i.e., the law. The last time I checked, the President doesn't have the authority to repeal or rescind a law. What am I missing here?
I am unsure if the waivers are authorized under the actual law, but that is immaterial (I seem to remember them being an extra-legal method of rewarding Obama's minions, exacted under regulations pursuant to the law). The executive branch determines who gets a waiver, and therefore the executive branch can immediately rescind all waivers.
It's really a no-brainer action - force the law to be employed as written and watch congress scramble to fix or repeal.
