Frederik Willem de Klerk DMS (Afrikaans pronunciation: ['frI@d@r@k 'v@l@m d@ 'klerk]; born 18 March 1936) is a South African politician who served as State President of South Africa from 1989 to 1994 and as Deputy President from 1994 to 1996. South Africa's last head of state from the era of white-minority rule, his government focused on dismantling the apartheid system and introducing universal suffrage.
De Klerk had been unhappy that changes had been made to the inauguration ceremony, rendering it multi-religious rather than reflecting the newly elected leader's particular denomination. When he was being sworn in, and the chief justice said "So help me God", de Klerk did not repeat this, instead stating, in Afrikaans: "So help me the triune God, Father, Son, and Holy Spirit". Mandela reappointed de Klerk's finance minister, Derek Keys, and retained Chris Stals, a former member of the Broederbond, as the head of the Central Bank. De Klerk supported the coalition's economic policies, stating that it "accepted a broad framework of responsible economic policies". De Klerk's working relationship with Mandela was often strained, with the former finding it difficult adjusting to the fact that he was no longer president. De Klerk also felt that Mandela deliberately humiliated him, while Mandela found de Klerk to be needlessly provocative in cabinet. One dispute occurred in September 1995, after Mandela gave a Johannesburg speech criticising the National Party. Angered, de Klerk avoided Mandela until the latter requested they meet; when they ran into each other, they publicly argued in the street. Mandela later expressed regret for their disagreement but did not apologise for his original comments. De Klerk was also having problems from within his own party, some of whose members claimed that he was neglecting the party while in the government. Many in the National Party--including many members of its executive committee--were unhappy with the other parties agreed upon a new constitution in May 1996. The party had wanted the constitution to guarantee that it would be represented in the government until 2004, although it did not do this. On 9 May, de Klerk announced that the National Party would withdraw from the coalition government. The decision shocked several of his six fellow Afrikaner cabinet colleagues; Pik Botha, for example, was left without a job as a result. Roelf Meyer reported feeling betrayed by de Klerk's act, while Leon Wessels thought that de Klerk had not tried hard enough to make the coalition work. De Klerk announced that he would lead the National Party in vigorous opposition to Mandela's government, stating that he wanted to ensure "a proper multi-party democracy, without which there may be a danger of South Africa lapsing into the African pattern of one-party states".

Why was their relationship strained?

De Klerk also felt that Mandela deliberately humiliated him, while Mandela found de Klerk to be needlessly provocative in cabinet.

Durant was born on September 29, 1988, in Washington, D.C., to Wanda (nee Durant) and Wayne Pratt. When Durant was an infant, his father deserted the family; Wanda and Wayne eventually divorced, and Durant's grandmother Barbara Davis helped raise him. By age 13, his father re-entered his life and traveled the country with him to basketball tournaments. Durant has one sister, Brianna, and two brothers, Tony and Rayvonne.
On July 4, Durant announced his intentions to sign with the Warriors in The Players' Tribune. The move was received negatively by the public and NBA analysts, with many comparing it to LeBron James's 2010 off-season departure from the Cleveland Cavaliers to join the Heat. On July 7, Durant officially signed with Golden State on a two-year, $54.3 million contract with a player option after the first year. Reflecting on the move for Sports Illustrated, Ben Golliver wrote, "He chose an ideal roster fit and a shot at playing for the highest-scoring offense the NBA has seen in decades. He chose life alongside Stephen Curry and Klay Thompson, the greatest shooting backcourt in history, and he chose to go against Andre Iguodala and Draymond Green, two elite defenders, in practices rather than in Western Conference finals games." Durant made his debut for the Warriors on October 25 against the San Antonio Spurs, scoring a team-high 27 points in a 129-100 loss. On November 26, he recorded 28 points, 10 rebounds, five assists, and a career-high six blocked shots in a 115-102 win over the Minnesota Timberwolves, becoming the first player in team history to finish with at least 25 points, 10 rebounds, five assists, and five blocks in a single game. On February 11, in his first game back in Oklahoma City since leaving for Golden State, Durant scored 34 points while being booed throughout the night as he helped the Warriors defeat the Thunder for the third time that year. In March, Durant suffered a Grade 2 MCL sprain and a tibial bone bruise, which forced him to miss the final 19 games of the season. Golden State finished the year with a 67-15 record and entered the playoffs as the No. 1 seed. Durant returned from injury in time for the playoffs and helped the Warriors advance to their third consecutive Finals while becoming the first team in league history to start the postseason 12-0. In Game 1 of the series, Durant had 38 points, eight rebounds, and eight assists to lead the Warriors past LeBron James and the defending champion Cleveland Cavaliers, 113-91. He helped the Warriors go up 3-0 in the series with a 31-point effort in Game 3, including the go-ahead 3-pointer with 45.3 seconds left in regulation. In Game 5, he scored 39 points to go with seven rebounds and five assists in a series-clinching 129-120 win. For the Finals, Durant was the Golden State's top scorer in every game, averaging 35.2 points, 8.4 rebounds, and 5.4 assists while shooting 55.5 percent from the field, 47.4 percent from three-point range, and 92.7 percent from the free throw line. He was subsequently named the Bill Russell NBA Finals Most Valuable Player.
