I can't imagine that Trump would think having Hillary's emails would be a good thing anyway. If he used anything from them in the campaign he would have been viciously attacked for peeking at an old lady's emails about Wedding plans, Yoga lessons and possibly her under-drawers. The press had already laid out how they were going to treat that.
Yes, that's true, but Don Jr accepted the meeting Veselnitskaya under the pretense she had information the Clinton campaign was accepting laundered foreign contributions. There's no actual crime in getting the information, unless the admin later followed through on an agreement - lifting of sanctions, for example.
If they had gotten anything from the meeting without offering or providing something in return, it wouldn't be illegal, but the media and left would still complain about interference by foreign power. That is kind of silly, considering we often exchanged information on various topics. For instance, we gave them information on a terrorist plot in St Petersburg recently. Conversely, they had warned us years ago about the Tsarnaev brothers. Were they trying to interfere in our domestic tranquility by telling us about them?
