Iran and the United States have had no formal diplomatic relations since 7 April 1980. Instead, Pakistan serves as Iran's protecting power in the United States, while Switzerland serves as the United States' protecting power in Iran. Contacts are carried out through the Iranian Interests Section of the Pakistani Embassy in Washington, D.C., and the US Interests Section of the Swiss Embassy in Tehran. In August 2018, Supreme Leader of Iran Ali Khamenei banned direct talks with the United States. According to the US Department of Justice, Iran has since attempted to assassinate US officials and dissidents, including US President Donald Trump.
The Logan Act is a United States federal law that criminalizes the negotiation of a dispute between the United States and a foreign government by an unauthorized American citizen. The intent behind the Act is to prevent unauthorized negotiations from undermining the government's position. 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 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, punishable with imprisonment for up to three years.
