Document 6: Father's Day: A bill to accord national recognition of the holiday was introduced in Congress in 1913. In 1916, President Woodrow Wilson went to Spokane to speak at a Father's Day celebration and he wanted to make it an officially recognized federal holiday, but Congress resisted, fearing that it would become commercialized. US President Calvin Coolidge recommended in 1924 that the day be observed throughout the entire nation, but he stopped short at issuing a national proclamation. Two earlier attempts to formally recognize the holiday had been defeated by Congress. In 1957, Maine Senator Margaret Chase Smith wrote a Father's Day proposal accusing Congress of ignoring fathers for 40 years while honoring mothers, thus ``(singling) out just one of our two parents ''. In 1966, President Lyndon B. Johnson issued the first presidential proclamation honoring fathers, designating the third Sunday in June as Father's Day. Six years later, the day was made a permanent national holiday when President Richard Nixon signed it into law in 1972.

Document 13: Federal Bureau of Investigation: During the September 11, 2001 attacks on the World Trade Center, FBI agent Leonard W.

Within months after the attacks, FBI Director Robert Mueller, who had been sworn in a week before the attacks, called for a re-engineering of FBI structure and operations.

Document 15: Federal Bureau of Investigation: Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort (the Venona project)—with which the FBI was heavily involved—broke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project but failed to notify the Central Intelligence Agency (CIA) until 1952. Another notable case is the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.
