Why in the world would Donald Trump Jr. take this meeting?

federal election law prohibits soliciting or accepting “anything of value … in connection with” an election from a foreign national.

.. Trump Jr.’s false and misleading statements on his involvement with Russians add to the argument that this is a man behaving as if he had something to hide. Asked by the New York Times in March whether he had ever discussed “government policies related to Russia,” Trump Jr. replied, “a hundred percent no.” Then, confronted by the Times about the Veselnitskaya meeting, he first said the participants “primarily discussed a program about the adoption of Russian children,” before acknowledging, the next day, that in fact it concerned opposition research on Clinton.
