Question: Sara Jane Moore, is an American citizen best known for attempting to assassinate US President Gerald Ford in 1975, Moore and Lynette "Squeaky" Fromme are the only two women to have attempted to assassinate an American president, "Squeaky" Fromme (born October 22, 1948) is an American would-be assassin, a member of which infamous family, she was sentenced to life imprisonment?
Context: On September 5, 1975, Charles Manson Family cult member Lynette "Squeaky" Fromme attempted to kill United States President Gerald Ford in Sacramento, California.  She wanted to make a statement to people who refused to halt environmental pollution and its effects on Air, Trees, Water, and Animals (ATWA).  Although Fromme stood a little more than an arm's length from Ford that Friday morning and pointed a M1911 pistol at him in the public grounds of the California State Capitol building, her gun failed to fire and no one was injured.  After the assassination attempt, Ford continued to walk to the California state house, where he met with California governor Jerry Brown.  For her crime, Fromme spent 34 years in prison and was released on August 14, 2009 – two years and seven months after Ford's death.  The Gerald R. Ford Presidential Museum in Grand Rapids, Michigan, later received the M1911 pistol used in the assassination attempt as a gift, and the gun was put on display. George Spahn (February 11, 1889 – September 22, 1974) was a rancher who once owned the Spahn Ranch near Chatsworth, Los Angeles, California.  Spahn (as did previous owner William S. Hart) rented the ranch to the movie industry to film Westerns.  At the ranch, he housed Charles Manson and his followers.  The 1969 murders of actress Sharon Tate and six others by Manson's devotees were allegedly hatched at the Spahn Ranch.  Manson persuaded Spahn to permit "the Family" to live at his ranch.  Manson ordered the Family women to have sex with the then nearly blind 80-year-old.  The women also acted as seeing eye guides for Spahn.  Spahn nicknamed all the Manson girls—Squeaky, Sadie Mae, Ouisch, etc.  According to Manson Family member Paul Watkins, notorious Mansonite Lynette "Squeaky" Fromme got her nickname because of the sound she made when Spahn ran his hand up her thigh.  Family member Charles Watson has written that his own nickname, "Tex", was given to him by Spahn, who recognized his Texas accent.

The Senator Hotel (officially Hotel Senator) (1924–1979) was a nine-story, 400-room Italian Renaissance-style hotel in Sacramento, California located at 12th and L streets across from the California State Capitol building that served as a nexus of California political and social activity for more than 50 years.  Opened in 1924, the Senator Hotel was where Arthur Samish, one of the most influential and powerful individual lobbyists in the history of California, maintained a suite during the 1930s and 1940s.  President Gerald Ford spent the night at the Senator Hotel before the September 5, 1975, assassination attempt on him by cultist Manson family disciple Squeaky Fromme.  Although the Senator Hotel was listed on the National Register of Historic Places in May 1979, the hotel was closed two months later and shuttered with panels placed over the windows that same year.  The structure was renovated and then reopened in 1983 as an office building under the name Senator Hotel Office Building, giving lobbyists short-walking-distance access to California's state politicians.
