Donald Trump is the man in office. Hillary Clinton has nothing to do with anything.
However Clinton may or may not violated the Constitution is absolutely irrelevant to the question of whether Trump is violating it now.
Because we're trying to ascertain if the complainers are genuinely principled or partisan hacks. I've a feeling most of them would be turning a blind eye if it wasn't trump.
For this reason it's helpful to understand the motives of those putting forth a particular argument.
I have a rule, and I think it's a good one. When I hear some political rhetoric I ask myself "if the parties were reversed would this person still be saying the same thing?" If the answer is no, I ignore that person. This cuts out about 97% of all political discussion and saves a lot of time.
I just think it's odd to say that Trump should be impeached for something his opponent did while in office.
Seems to work like a charm to derail conversation about the real topic at hand.

For context, Doug Band is a very close Clinton associate and he's discussing an initiative apparently launched by Chelsea Clinton to investigate money within the Clinton Foundation (which is also mentioned in some of the other Podesta emails).
