It's not very long, can quote the whole of it:
Any citizen of the United States, wherever he may be, who, without authority of the United States, directly or indirectly commences or carries on any correspondence or intercourse with any foreign government or any officer or agent thereof, with intent to influence the measures or conduct of any foreign government or of any officer or agent thereof, in relation to any disputes or controversies with the United States, or to defeat the measures of the United States, shall be fined under this title or imprisoned not more than three years, or both.Learned of it because 47 Republican Congresspersons appear to be violation of it. Hence the trending hashtag #47traitors ...
This section shall not abridge the right of a citizen to apply, himself or his agent, to any foreign government or the agents thereof for redress of any injury which he may have sustained from such government or any of its agents or subjects.

Here's the letter all the fuss is about: [original document]
In short, I'm not about to get my undies in a bunch and sign a petition requesting the 47 be charged, though it would oh so fun to watch Eric Holder make them sweat. Still, is this the brand the GOP is after? Knobshiners for Netanyahu? Chickenhawk Traitors?
