Presidency of Barrack Obama

Barack Obama's tenure as the 44th president of the United States began with his first inauguration on January 20, 2009, and ended on January 20, 2017. A Democrat from Illinois, Obama took office following a decisive victory over Republican nominee John McCain in the 2008 presidential election. Four years later, in the 2012 presidential election, he defeated Republican nominee Mitt Romney to win re-election. Obama is the first African American president, the first multiracial president, the first non-white president, and the first president born in Hawaii.

Obama's accomplishments during the first 100 days of his presidency included signing the Lilly Ledbetter Fair Pay Act of 2009 relaxing the statute of limitations for equal-pay lawsuits; signing into law the expanded State Children's Health Insurance Program(S-CHIP); winning approval of a congressional budget resolution that put Congress on record as dedicated to dealing with major health care reform legislation in 2009; implementing new ethics guidelines designed to significantly curtail the influence of lobbyists on the executive branch; breaking from the Bush administration on a number of policy fronts, except for Iraq, in which he followed through on Bush's Iraq withdrawal of U.S. troops; supporting the UN declaration on sexual orientation and gender identity; and lifting the 7½-year ban on federal funding for embryonic stem cell research. Obama also ordered the closure of the Guantanamo Bay detention camp, in Cuba, though it remains open. He lifted some travel and money restrictions to the island.

Obama signed many landmark bills into law during his first two years in office. The main reforms include: the Affordable Care Act, sometimes referred to as "the ACA" or "Obamacare", the Dodd–Frank Wall Street Reform and Consumer Protection Act, and the Don't Ask, Don't Tell Repeal Act of 2010. The American Recovery and Reinvestment Act and Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act served as economic stimuli amidst the Great Recession. After a lengthy debate over the national debt limit, he signed the Budget Control Act of 2011 and the American Taxpayer Relief Act of 2012. In foreign policy, he increased U.S. troop levels in Afghanistan, reduced nuclear weapons with the United States–Russia New START treaty, and ended military involvement in the Iraq War. In 2011, Obama ordered the drone-strike killing in Yemen of al-Qaeda operative Anwar al-Awlaki, who was an American citizen. He ordered military involvement in Libya in order to implement UN Security Council Resolution 1973, contributing to the overthrow of Muammar Gaddafi. He also ordered the counterterrorism raid that killed Osama bin Laden.

After winning re-election by defeating Republican opponent Mitt Romney, Obama was sworn in for a second term on January 20, 2013. During this term, he condemned the 2013 Snowden leaks as unpatriotic, but called for more restrictions on the National Security Agency (NSA) to address privacy issues. Obama also promoted inclusion for LGBT Americans. His administration filed briefs that urged the Supreme Court to strike down same-sex marriage bans as unconstitutional (United States v. Windsor and Obergefell v. Hodges); same-sex marriage was legalized nationwide in 2015 after the Court ruled so in Obergefell. He advocated for gun control in response to the Sandy Hook Elementary School shooting, indicating support for a ban on assault weapons, and issued wide-ranging executive actions concerning global warming and immigration. In foreign policy, he ordered military interventions in Iraq and Syria in response to gains made by ISIL after the 2011 withdrawal from Iraq, promoted discussions that led to the 2015 Paris Agreement on global climate change, drew down U.S. troops in Afghanistan in 2016, initiated sanctions against Russia following its annexation of Crimea and again after interference in the 2016 U.S. elections, brokered the Joint Comprehensive Plan of Action nuclear deal with Iran, and normalized U.S. relations with Cuba. Obama nominated three justices to the Supreme Court: Sonia Sotomayor and Elena Kagan were confirmed as justices, while Merrick Garland was denied hearings or a vote from the Republican-majority Senate.
