Fact:
I hope people are looking up the word in a dictionary, but for Encarta the first three definitions have something to do with truth, the fourth is a term of law, so he certainly would not use that one. Anyway, this must mean truth can change or maybe we will wait for the dictionary to change.

What can change is that a fact can be trustworthy or not. That is apparently what has changed. Then not, again.

I do believe that the president claimed that critics were wrong and that he should be trusted with the decision. That seems not to have changed, while the facts have. Not. That seems to have changed or it never mattered.

You can have your cake and eat it too, but crow...
