Barack Obama was the first African-American to serve as President of the United States. A graduate of Harvard Law School, Obama served as an Illinois State Senator, and U.S. Senator from the same state. He announced his campaign for President of the United States after one term in Congress, competing with fellow Senator Hillary Clinton for the Democratic nomination. In his first term in the executive office, Barack Obama faced a recession and rising federal deficit, war in the Middle East, and political division at home. He was re-elected to a second term in November 2012, winning the bid over Republican candidate Mitt Romney. President Obama's second term was marked by domestic mass shootings, the threat of terrorism, and the implementation of the Affordable Care Act.
