Umar (Arabic: عمر ابن الخطاب, Transliteration: `Umar ibn Al-Khattāb, Umar Son of Al-Khittab, c. 586–590 CE– 7 November 644), also known as Omar, Farooq the Great was the most powerful of the four Rashidun Caliphs and one of the most powerful and influential Muslim rulers in history. He was a sahabi (companion) of the Islamic prophet Muhammad. He succeeded Caliph Abu Bakr (632–634) as the second Caliph of Rashidun Caliphate on 23 August 634. He was an expert jurist and is best known for his justice, that earned him the title Al-Farooq (The one who distinguishes between right and wrong). Under Umar the Islamic empire expanded at an unprecedented rate ruling the whole Sassanid Persian Empire and more than two thirds of the Eastern Roman Empire. His brilliantly coordinated multi-prong attacks against the Sassanid Persian Empire resulted in the conquest of the Persian empire in less than two years. His legislative abilities and firm political and administrative control over a rapidly expanding empire marked his reputation as a great political and military leader. It was Umar, who for the first time in 500 years since their expulsion from the Holy Land, allowed Jews to practice their religion freely and live inside Jerusalem.^{[citation needed]}

Donald John Trump, Sr. (born June 14, 1946) is an American business magnate, television personality and author. He is the chairman and president of The Trump Organization and the founder of Trump Entertainment Resorts. Trump's extravagant lifestyle, outspoken manner and role on the NBC reality show The Apprentice have made him a well-known celebrity who was No. 17 on the 2011 Forbes Celebrity 100 list. He is well-known as a real-estate developer who amassed vast hotel, casino, and other real-estate properties, in the New York City area and around the world.

Trump is the son of Fred Trump, a wealthy New York City real-estate developer. He worked for his father's firm, Elizabeth Trump & Son, while attending the Wharton School of the University of Pennsylvania, and in 1968 officially joined the company. He was given control of the company in 1971 and renamed it The Trump Organization.

In 2010, Trump expressed an interest in becoming a candidate for President of the United States in the 2012 election. In May 2011, he announced he would not be a candidate, but a few weeks later he said he had not completely ruled out the possibility. In December 2011, Trump was suggested as a possible Vice Presidential selection by Michele Bachmann. Bachmann has since suspended her presidential campaign.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
