Sanders participated in an anti-war march following the United States invasion of Grenada and criticized the United States for its hypocritical condemnation of the Soviet invasion of Afghanistan and Poland while simultaneously invading Grenada. Sanders also wrote a letter to Senator Patrick Leahy asking him about the role the CIA played in the overthrowing of Maurice Bishop, the leader of Grenada, stating that “I am curious about the role the C.I.A. had in the overthrow of Maurice Bishop. Certainly, the whole Grenadian operation had all the ingredients of a C.I.A. scenario. There was the required disruption, murder, confusion and, finally, the military action to restore ‘law and order,'”. A resolution calling for the withdraw of United States soldiers from Grenada failed after a five to five vote in the city council. Sanders participated in an anti-war march in Washington, D.C., which was attended by over 50,000 people.
