I am sure we are all reading about Donny Jr's E-mails with Russia.

Let's assume what what is being reported is true

Let's, for a moment ignore the failure to report/lying as that is a different issue.

Was Jr, communicating with Russian nationals, in this context, in violation of a federal law?

I don't care if we did not like it, or if it was a poor decision. I just want to know if there was anything illegal about what he did.

I can't find any federal statutes that address this (other than the concealment and lying). None of the news media is citing any actual laws that Jr might have broken.

Which raises the question that if what he did was not illegal, why did he conceal it?

Whether his contact was legal or illegal is a pretty important issue. And if what he did was illegal, then an actual federal law should be cited.
