"I am sorry that they are finding themselves in this situation based on assurances they got from me."Sorry, mr. president, people do not find themselves in this situation based on your "assurances." They find themselves there because of your actions and despite your lies. Period.
In a twisted way, though, you have a point: I'll concede that without those lies (and IRS crimes), you might not be President now, but blaming the assurances is just another way of saying, "It's not my fault."
And, by the way, does this mean the "junk insurance policies" from "bad apple" insurers are NOT the problem you said they were last week? If those things are still true this week, why are you sorry? Isn't everyone still better off?
