Logan Act - Wikipedia, the free encyclopedia
a United States federal law that forbids unauthorized citizens from negotiating with foreign governments. It was intended to prohibit unauthorized United States citizens from interfering in relations between the United States and foreign governments. The Act was passed following George Logan's unauthorized negotiations with France in 1798, and was signed into law by President John Adams on January 30, 1799. The Act was last amended in 1994, and violation of the Logan Act is a felony.
