Background: Pieter Willem Botha, DMS (Afrikaans pronunciation: ['pit@r 'v@l@m 'bU@ta]; 12 January 1916 - 31 October 2006), commonly known as "P. W." and Die Groot Krokodil (Afrikaans for "The Big Crocodile"), was the leader of South Africa from 1978 to 1989, serving as the last Prime Minister from 1978 to 1984 and the first executive State President from 1984 to 1989. First elected to Parliament in 1948, Botha was an outspoken opponent of majority rule and international communism. However, his administration did make concessions towards political reform, whereas internal unrest saw widespread human rights abuses at the hands of the government. Botha resigned the leadership of the ruling National Party in February 1989 after suffering a stroke and six months later was coerced to leave the presidency as well.
Context: At age 30, Botha was elected head of the National Party Youth in 1946, and two years later won a race for the House of Assembly as representative of George in the southern Cape Province in the general election which saw the beginning of the National Party's 46-year tenure in power. In 1958 Botha was appointed Deputy Minister of Internal Affairs by Hendrik Verwoerd, and in 1961 advanced to Minister of Coloured Affairs. He was appointed Minister for Defence by Verwoerd's successor B.J. Vorster, upon Verwoerd's murder, in 1966. Under his 14 years as its leader, the South African Defence Force reached a zenith, at times consuming 20% of the national budget, compared to 1.3% in 1968, and was involved in the South African Border War. When Vorster resigned following allegations of his involvement in the Muldergate Scandal in 1978, Botha was elected as his successor by the National Party caucus, besting the electorate's favourite, 45-year-old Foreign Minister Pik Botha. In the final internal ballot, he beat Connie Mulder, the scandal's namesake, in a 78-72 vote.  Botha was keen to promote constitutional reform, and hoped to implement a form of federal system in South Africa that would allow for greater "self-rule" for black homelands (or Bantustans), while still retaining the supremacy of a white central government, and foremost expand the rights of Coloureds (South Africans of mixed ancestry) and Asians in order to widen support for the government. Upon enacting the reforms, he remarked in the House of Assembly; "We must adapt or die."  On becoming head of the government, Botha retained the defence portfolio until October 1980, when he appointed chief of the South African Defence Force, General Magnus Malan, his successor. From his ascension to the cabinet, Botha pursued an ambitious military policy designed to increase South Africa's military capability. He sought to improve relations with the West - especially the United States - but with mixed results. He argued that the preservation of the apartheid government, though unpopular, was crucial to stemming the tide of African Communism, which had made in-roads into neighbouring Angola and Mozambique after these two former Portuguese colonies obtained independence.  As Prime Minister and later State President, his greatest parliamentary opponents were Harry Schwarz and Helen Suzman of the Progressive Federal Party until 1987, when his former cabinet colleague Andries Treurnicht's new Conservative Party became the official opposition on a strictly anti-concessionist agenda.  In 1977, as Minister of Defence he began a secret nuclear weapons program, which culminated in the production of six nuclear bombs destroyed only in the early 1990s. He remained steadfast in South Africa's administration of the neighbouring territory South-West Africa, particularly while there was a presence of Cuban troops in Angola to the north. Botha was responsible for introducing the notorious police counter-insurgency unit, Koevoet. He was also instrumental in building the South African Defence Force's strength. Adding momentum to establishing units such as 32 Battalion. South African intervention in support of the rebel UNITA (Dr. Jonas Savimbi, a personal friend) movement in the Angolan Civil War continued until the late 1980s, terminating with the Tripartite Accord. To maintain the nation's military strength, a very strict draft was implemented to enforce compulsory military service for white South African men.
Question: What happened to him after that?
Answer: and two years later won a race for the House of Assembly

Background: Henry Hill, Jr. was born on June 11, 1943 in Manhattan, New York, to Henry Hill, Sr., an Irish immigrant and electrician, and Carmela Costa Hill, a Sicilian. The working-class family consisted of Henry and his eight siblings who grew up in Brownsville, a poorer area of the East New York section of Brooklyn. From an early age, Hill admired the local mobsters who socialized across the street from his home, including Paul Vario, a capo in the Lucchese crime family. In 1955, when Hill was 11 years old, he wandered into the cabstand across the street looking for a part-time after-school job.
Context: Hill testified against his former associates to avoid a possible execution by his crew or going to prison for his crimes. His testimony led to 50 convictions.  Jimmy Burke was given 20 years in prison for the 1978-79 Boston College point shaving scandal, involving fixing Boston College basketball games. Burke was also later sentenced to life in prison for the murder of scam artist Richard Eaton. Burke died of lung cancer while serving his life sentence, on April 13, 1996, at the age of 64.  Paul Vario received four years for helping Henry Hill obtain a no-show job to get him paroled from prison. Vario was also later sentenced to ten years in prison for the extortion of air freight companies at JFK Airport. He died of respiratory failure on November 22, 1988, at age 73 while incarcerated in the FCI Federal Prison in Fort Worth.  Hill, his wife Karen, and their two children (Gregg and Gina) entered the U.S. Marshals' Witness Protection Program in 1980, changed their names, and moved to undisclosed locations in Omaha, Nebraska; Independence, Kentucky; Redmond, Washington; and Seattle, Washington. In Seattle, Hill hosted backyard cookouts for his neighbors, and on one occasion, while under the influence of a combination of liquor and drugs, he revealed his true identity to his guests. To the ire of the federal marshals, they were forced to relocate him one final time to Sarasota, Florida. There, a few months had passed, and Hill repeated the same breach of security, causing the government to finally expel him from the Federal Witness Protection Program.
