A liar telling the truth occasionally when it fits their needs, does not negate the lies they've told before.
Telling a lie and then telling the truth a couple of times does not make them honest. If fact, quite the contrary. It makes them dishonest.
This is why you cannot trust someone (HilLIARy Clinton) or something (Washington ComPost) ever again, if they have lied to you before.
Once a liar, always a liar.
