Barack Obama was re-elected to a second four-year term in 2012.
As President, Obama signed the Paris Accords, which was a treaty of agreement of 195 countries to try to reduce carbon pollution, to slow down the rise in global temperatures and ocean levels. He dealt with wars in Iraq, Afghanistan, Syria, and strained relations with Iran. He made good on his campaign promise to draw down (reduce) the number of military serving abroad, bringing tens of thousands of soldiers back home.
Barack Obama was President when Osama bin Laden, the supposed mastermind behind the September 11, 2001 attacks was located in a hideout in the country of Pakistan. Obama took this 'intel' seriously, and made sure it came from reliable informants. Obama coordinated with his elite military leaders, considered the personnel and weapons options available to him, and approved the mission to kill bin Laden. The successful secret mission was carried out by heroic Navy Seals. (Read more about this at:

In 2016, a crisis of public health came to light in the city of Flint, Michigan. Flint city government officials, for economic reasons (to save money), changed the source of water piped into the city of Flint. The new water source created a contamination of the city's underground pipes, resulting in the water coming out of residents' faucets to contain lead and other carcinogens (toxins). Ingesting lead is especially harmful to children's brain development. The concerned citizens appealed to Flint city and Michigan state officials to solve the problem, but they did little to help. Upset citizens then appealed to President Obama for help. Obama traveled from Washington, D.C. to Michigan in a highly publicized event. The people of Flint expected action, but only received promises from the President and little in the way of meaningful solutions. The majority of people in Flint were disappointed by Obama's inaction. (Read more about this crisis at:

In his last year in office, Obama spoke of the progress made in Civil Rights and what lay ahead. He said, “Our union is not yet perfect, but we are getting closer,” and... “And that’s why we celebrate, mindful that our work is not yet done.”
Obama played a lot of golf, as well as basketball, as forms of recreation during his Presidency.
Obama's chosen Secretary of State was Hillary Clinton, and his Vice President was Joe Biden. In each of their Presidential Campaigns he provided some support, but generally remained out of the public eye.
