The Logan Act (, , enacted ) is a United States federal law that criminalizes negotiation by unauthorized American citizens with foreign governments having a dispute with the United States. The intent behind the Act is to prevent unauthorized negotiations from undermining the government's position. The Act was passed following Senator 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 amended in 1994, changing the penalty for violation from "fined $5,000" to "fined under this title"; this appears to be the only amendment to the Act. Violation of the Logan Act is a felony.
