I see the hypocrisy in complaining about Obama and not Trump, just like complaining about Trump and not Obama. Those are strongly hypocritical, both of them (is seeing and discussing one hypocritical when the other is not mentioned, too?).
Where I do not see hypocrisy is in thinking that wasting millions on an act that there was no purpose in is comparable to spending money on a vacation. Vacations cost a lot, and for presidents they cost way more. This is pretty obvious to even the most stupid among us (yes, Sappy, I'm talking to you with that). But, the comparison is in the merit. If we spend $35M on a solid gold submarine, knowing it would sink and never resurface, that would be a waste of money (see: Mueller Report). If we spend $100M on a world class nuclear submarine, and include $25k to furnish the CO's stateroom with awesome furniture, we could easily complain about the $25K (or, a portion of it, since the CO actually does need some furniture), but not the $100M because that's a cost of doing business.
Similarly, if we spend $100M on vacations, we can say that is arguably more than we hoped to spend, or that maybe he didn't need to go to a plush resort or something, but that's peanuts of complaint about the overall $100M. Meanwhile, we spent $35M on something that never needed done, and was a total waste from every angle.
Yes, the argument has been made that investigations were continued under this hat that happened to already be happening before it and would have resulted in the money they recouped anyway, but since they were finished under the hat of a completely different intended investigation we should take credit for funds recovered. Kind of like saying you owe me for the oxygen you're breathing because I just mentioned it even though you already had all your oxygen without me mentioning it. No reasonable person would conflate those things like that, but the argument has been made.
