Obama celebrated his 51st birthday playing golf with a group of friends and aides at Andrews Air Force Base and plans for a quiet weekend at Camp David.
He is the 44th and current President of the United States and the first African American to hold the office.
Obama served as a U.S. Senator representing the state of Illinois from January 2005 to November 2008, when he resigned following his victory in the 2008 presidential election.
Obama was born in Honolulu, Hawaii. He 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.
As president, Obama signed economic stimulus legislation in the form of the American Recovery and Reinvestment Act of 2009 and the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 in response to the Late 2000s recession. Other major domestic policy initiatives include the Patient Protection and Affordable Care Act, the Dodd–Frank Wall Street Reform and Consumer Protection Act, the Don’t Ask, Don’t Tell Repeal Act of 2010, and the Budget Control Act of 2011. In foreign policy, Obama ended the Iraq War, increased troop levels in Afghanistan, signed the New START arms control treaty with Russia, ordered U.S. military involvement in Libya, and ordered the military operation that resulted in the death of Osama bin Laden. In May 2012, he became the first sitting U.S. president to openly support legalizing same-sex marriage.
