What is the "LOGAN ACT"? -How does it apply to Congressmen?

Question

Congressmen are "Civilians" while the Executive is Commisioned!
Should Some CongressPeople be asking Martha Stewart for deccorating tips?

What I am wondering about are the rules of Hierarchy. Chain of command so to say that establishes who is authorized in which branches to be the proper reopresentative for negotiations.
I believe that the restricyions are due to Commisioned and Non-Commisioned(IE Civilians)-of which Legislators fall into!

Answer 1

As for it applying to Congressmen I guess they need to have authority of the United States before proceeding.

The Logan Act is a United States federal law that forbids private citizens from negotiating with foreign governments. It was passed in 1799 and last amended in 1994.
Passed under the administration of President John Adams during tension between the U.S. and France, it was named for Dr. George Logan of Pennsylvania, who engaged in semi-negotiations with France during the Quasi-War.

Text of the law : 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.
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.
