Question: Sara Jane Moore, is an American citizen best known for attempting to assassinate US President Gerald Ford, in which year?
Context: Gerald Rudolph Ford Jr. (born Leslie Lynch King Jr.; July 14, 1913 – December 26, 2006) was an American politician who served as the 38th President of the United States from August 1974 to January 1977, following the resignation of Richard Nixon.  Prior to this he served eight months as the 40th Vice President of the United States, following the resignation of Spiro Agnew.  He was the first person appointed to the vice presidency under the terms of the 25th Amendment, and consequently the only person to have served as both Vice President and President of the United States without being elected to executive office.  Before his appointment to the vice presidency, Ford served 25 years as U.S. Representative from Michigan's 5th congressional district, the final nine of them as the House Minority Leader. Bobbie Kilberg (born Barbara Greene; October 25, 1944) is a Republican operative who has worked for Presidents Richard Nixon, Gerald Ford, George H.W. Bush, and George W. Bush.  Kilberg is currently the President and CEO of the Northern Virginia Technology Council and has been since 1998.  She was briefly an attorney with the Washington law firm of Arnold & Porter from 1971 to 1973.  Her White House experiences include serving on the staff of President Richard Nixon's Domestic Policy Council, serving under President Gerald Ford as Associate Counsel and serving for President George H.W. Bush as Deputy Assistant to the President for Public Liaison and as Director of the White House Office of Intergovernmental Affairs. Michael Gerald Ford (born March 14, 1950) is the oldest of four children of U.S. President Gerald R. Ford and Betty Ford.  Prior to his birth, Ford's mother wanted to name him after his father.  However, Ford's father had always disliked being called "Junior" and he refused to "inflict the nickname on any son."  The Fords settled on his name as a compromise. Sara Jane Moore (née Kahn; born February 15, 1930) is an American citizen best known for attempting to assassinate US President Gerald Ford in 1975.  She was given a life sentence for the attempted assassination and was released from prison on December 31, 2007, after serving 32 years.  Moore and Lynette "Squeaky" Fromme are the only two women to have attempted to assassinate an American president; both of their attempts were on Gerald Ford and both took place in California within three weeks of one another.  Mary Surratt, a woman, was convicted as a conspirator in the murder of Abraham Lincoln and hanged. Oliver Wellington "Billy" Sipple (November 20, 1941 – February 2, 1989) was a decorated US Marine and Vietnam War veteran.  On September 22, 1975, he bumped Sara Jane Moore as she fired a pistol at US President Gerald Ford in San Francisco, causing her to miss.  The subsequent public revelation that Sipple was gay turned the news story into a cause célèbre for LGBT rights activists, leading Sipple to unsuccessfully sue several publishers for invasion of privacy. Lynette Alice "Squeaky" Fromme (born October 22, 1948) is an American would-be assassin best known for attempting to assassinate U.S. President Gerald Ford in 1975.  A member of the infamous "Manson family", she was sentenced to life imprisonment for the assassination attempt and released on parole on August 14, 2009, after serving nearly 34 years. Whip Inflation Now (WIN) was a 1974 attempt to spur a grassroots movement to combat inflation in the US, by encouraging personal savings and disciplined spending habits in combination with public measures, urged by US President Gerald Ford.  The campaign was later described as "one of the biggest government public relations blunders ever". John "Jack" Gardner Ford (born March 16, 1952) is the second child and second son of U.S. President Gerald Ford and Betty Ford.  Married to Juliann Felando Ford on April 29, 1989 and they have two sons, Christian Gerald Ford (born October 14, 1997), and Jonathan August Ford (born November 29, 1999).  He is a 1970 graduate of T.C. Williams High School in Alexandria, Virginia.  He attended Utah State University, studying Forestry. In 1974, Republican President Richard Nixon was forced to resign following the Watergate Scandal.  Vice President Gerald Ford ascended to the presidency, leaving the office of vice president vacant.  Under the terms of the 25th Amendment, a vice presidential vacancy is filled when the president nominates a candidate who is confirmed by both houses of Congress.  On August 20, 1974, Ford announced his nomination of former New York Governor Nelson Rockefeller to fill the vacancy.  Ford also considered picking Tennessee Senator Howard Baker and former Republican National Committee Chairman George H.W. Bush.  Rockefeller was generally considered to be a liberal Republican, and Ford decided that picking Rockefeller would help his candidacy gain support in the 1976 presidential election.  The confirmation hearings for Rockefeller lasted for months, but Rockefeller was sworn in as the 41st Vice President of the United States on December 19, 1974.  Due to the pressure on Ford by the party conservatives, Rockefeller was ultimately passed over for the 1976 ticket, and Ford instead chose Bob Dole as his running mate.  Ford, however, regreted this move later. The 1975 LaGuardia Airport bombing occurred at 6:33 pm on Monday, December 29, 1975, near the TWA baggage reclaim terminal in LaGuardia Airport in East Elmhurst, New York City.  The blast killed 11 and seriously injured 74.  The bombing was never solved, with several suggested perpetrators, although investigators and historians believe that Croatian nationalists were the most likely.  The attack occurred in a four-year period of heightened terrorist attacks within the United States.  1975 was especially volatile, with bombings in New York City and Washington D.C. early that year and two assassination attempts on US President Gerald Ford.
