Barack Hussein Obama II (born August 4, 1961) is the 44th and current President of the United States, having taken office in 2009. He is the first African American to hold the office. Obama previously served as a United States senator from Illinois, from January 2005 until he resigned following his election to the presidency in November 2008.
A native of 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.
As president, Obama signed economic stimulus legislation in the form of the American Recovery and Reinvestment Act in February 2009 and the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 in December 2010. Other domestic policy initiatives include the Patient Protection and Affordable Care Act, the Dodd–Frank Wall Street Reform and Consumer Protection Act and the Don’t Ask, Don’t Tell Repeal Act of 2010. In foreign policy, Obama gradually withdrew combat troops from Iraq, increased troop levels in Afghanistan, signed an arms control treaty with Russia, and ordered enforcement of the United Nations-sanctioned no-fly zone over Libya in early 2011.
In April 2011, Obama announced his intention to seek re-election in the 2012 presidential election.
