The TL;DR summary of the Trump Tower meeting, by way of the Senate Committee testimony, seems to be “we wanted dirt on our opponent to help win the election, and were right eager to accept said help from Russia but this meeting failed to provide what we wanted to procure”. Which, as far as defenses go … not a great one.

While one is not meant to consider the ramification of a legal decision, Trump Jr’s testimony brings to mind prostitution sting operations. I would love to see the defendant claiming that they had not in fact engaged in an illegal activity. Sure they wanted to exchange money for sex. The sex was never provided; ipso facto the law was not broken. Case dismissed! Sorry to inconvenience you, upstanding citizen.
