The inauguration of Dilma Rousseff as the 36th President of Brazil took place on Saturday, January 1, 2011.
 This inauguration marked the beginning of the four-year term of Dilma Rousseff as President and Michel Temer as Vice President.
 The event had been awaited with some expectation, since Rousseff became the first woman in the history of Brazil to take office as President.
 It was also the first inaugural ceremony of the New Republic and of the democratic rule in which an outgoing President passed his office to a successor belonging to the same political party as him – the Workers' Party.
The Vice President of the Republic of Liberia is the second-highest executive official in Liberia, and one of only two elected executive offices along with the President.
 The Vice President is elected on the same ticket with the president to a six-year term.
 In the event of the death, resignation or removal of the president, the Vice President ascends to the presidency, which he or she holds for the remainder of their predecessor's term.
 The Vice President also serves as the President of the Senate and may cast a vote in the event of a tie.
 The current Vice President is Joseph Boakai, serving under President Ellen Johnson Sirleaf.
 He began his term on January 16, 2006.
The College of West Africa is a Methodist high school in Monrovia, Liberia.
 The school was opened in 1839 (as the "Monrovia Seminary"), making it one of the oldest European-style schools in Africa.
 It has produced many of Liberia's leaders and includes among its alumni Liberian President Ellen Johnson Sirleaf, the first woman elected as president in an African state, and Liberian Vice President Joseph Boakai.
Thomas Yaya Nimely (born 1956) is a politician in Liberia.
 In 2003 he became the leader of the Movement for Democracy in Liberia (MODEL), which soon became Liberia's second largest rebel group.
 Following the exile of President Charles Taylor, Nimely led his group into the transitional government which was formed on 14 October 2003.
 He then served as the foreign minister of Liberia until February 2006, when the elected President Ellen Johnson Sirleaf took office and established her new cabinet.
The 2016 presidential campaign of Marco Rubio, the junior United States Senator from Florida, and former Speaker of the Florida House of Representatives, was formally announced on April 13, 2015, at an event at the Freedom Tower in Downtown Miami.
 Early polling showed Rubio, who was considered a potential candidate for Vice President by Republican presidential nominee Mitt Romney in 2012, as a frontrunner candidate for the Republican nomination for President of the United States in 2016 since at least the end of the 2012 election.
 Rubio was the second Cuban American to run for President of the United States, declaring approximately three weeks after fellow Republican Ted Cruz.
 He suspended his campaign on March 15, 2016, after finishing second in the primary for Florida, his home state.
 Turning 45 in 2016, Rubio would've been the third youngest president to take office, the others being Theodore Roosevelt and John F. Kennedy, who took office at ages 42 and 43 respectively.
 Rubio would've also been the first president of Latin American culture, as he was born to Cuban parents, as well as the first Florida native to become president.
John G. Bestman (born December 1, 1939 in Liberia) is a former two times minister of finance in Liberia, one time minister of telecommunication & post, and governor of the Central Bank of Liberia.
 In 2005, Bestman was successful campaign manager for Ellen Johnson Sirleaf election to become the first female president of Africa.
 John also is member of the board of the Central Bank and adviser to the president.
George W. Wallace Jr. (born on May 30, 1938) was the foreign minister of Liberia from 2006 to 2007.
 He took office early in 2006, having been appointed to the cabinet of the incoming president Ellen Johnson Sirleaf and confirmed by the Senate.
 Wallace has had a long career as a Liberian diplomat and ambassador through all of its governments during the past several decades.
 In a cabinet reshuffle on August 22, 2007, he was replaced as foreign minister by Olubanka King Akerele and became special adviser to President Johnson Sirleaf instead.
Corruption is endemic at every level of the Liberian government.
 Corruption is not specifically a punishable crime under Liberian law.
 When President Sirleaf took office in 2006, she announced that corruption was “the major public enemy.”
Dr. Edward Binyah Kesselly was a minister in the Cabinet of William R. Tolbert, Jr. in Liberia.
 During the late 1970s, he headed the Ministry of Posts and Telecommunications; President Tolbert appointed him to the ministry on February 3, 1978.
 His predecessor as head of Posts and Telecommunications, J. Jenkins Peel, had resigned that office to become the Minister of Information, Cultural Affairs and Tourism, in which Kesselly had previously served as an administrator for five years.
 One of the few members of Tolbert's cabinet to survive the military coup d'état that overthrew Tolbert's government in 1980, he founded the Unity Party in 1984.
 Buried in Monrovia after his 1993 death, he was re-buried eighteen years later at his hometown of Nyama-Kamadu in Quardu-Gbomi District of Lofa County.
 Among the speakers at the pomp-filled reburial ceremony were Bureau of Maritime Authority Commissioner Edward Binyah Kesselly, Jr., his eldest son, and Unity Party standard bearer Ellen Johnson Sirleaf, the President of Liberia.
Ellen Johnson Sirleaf (born 29 October 1938) is a Liberian politician who serves as the 24th and current President of Liberia since 2006.
 Sirleaf is the first elected female head of state in Africa.
