The United States reinstated sanctions against Yugoslavia in March 1998 when the Kosovo War started. Shortly after the controversies at Račak and Rambouillet, American diplomat Richard Holbrooke traveled to Belgrade in March 1999 to deliver the final ultimatum requesting entry of UN forces into Kosovo. Milošević rejected the ultimatum, and the United States completely severed ties with Yugoslavia on March 23, 1999. Bill Clinton became the first president to declare war while bypassing a Congressional majority. The establishment of the bombing campaign was contested by one of the tightest votings (213-213) in the entire history of the House of Representatives. The United States declared war on Yugoslavia on March 24, 1999 to take part in Operation Allied Force led by U.S. general Wesley Clark. Out of all the territories in Yugoslavia at the time, Serbia was bombed the most due to its concentration of military targets. As a result of Slobodan Milošević granting entry to KFOR in Kosovo, the war against Yugoslavia ceased on June 10, 1999.
