Threatening the President of the United States is a felony under United States Code Title 18, Section 871.[1][2][3][4] It consists of knowingly and willfully mailing or otherwise making "any threat to take the life of, to kidnap, or to inflict bodily harm upon the President of the United States". This also includes presidential candidates and former Presidents. The United States Secret Service investigates suspected violations of this law and monitors those who have a history of threatening the President. Threatening the President is considered a political offense.[5] Immigrants who commit this crime can be deported.
