Iftar is a ritual observed by Muslims at the end of the daily fast during the month of Ramadan. Muslims break the fast at sundown–a time prescribed by local clerics, based on astronomical calculations–by drinking water and eating dates. Families, other social groups, and mosques then hold elaborate meals, and in Muslim countries, restaurants may put out tables and serve food to the public.

President George W. Bush inaugurated the practice of White House iftar dinners. During his tenure in office, Muslim extremists occasionally called for a boycott of his invitations. Iftar events were also held on the Hill, and provoked debate because of the participation of the radical Council on American Islamic Relations (CAIR).
