Barack Obama biography

He signed the Budget Control Act of 2011 in effort to rein in government spending and prevent the government from defaulting on its financial obligations. The act also called for the creation of a bipartisan committee to seek solutions to the country's fiscal issues, but the group failed to reach any agreement on how to solve these problems.

Obama has also handled a number of military and security issues during his presidency. In 2011, he helped repeal the military policy known as "Don't Ask,

Don't Tell," which prevented openly gay troops from serving in the U.S. Armed Forces. He also gave the green light to a 2011 covert operation in Pakistan, which led to the killing of infamous al-Qaeda leader Osama bin Laden by a team of U.S. Navy SEALs.

Obama made headlines again in June 2012, when a mandate included in his Patient Protection and Affordable Care Act (initiated in 2010) was upheld by the U.S. Supreme Court, thus allowing other important pieces of the law to stay intact. The law includes free health screenings for certain citizens, restrictions to stringent insurance company policies and permission for citizens under age 26 to be insured under parental plans, among several other provisions. In a 5-4 decision, the Court voted to uphold the mandate under which citizens are required to purchase health insurance or pay a tax—a main provision of Obama's health-care law—stating that while the mandate is unconstitutional, according to the Constitution's commerce clause, it falls within Congress' constitutional power to tax.

2012 Re-Election

As he did in 2008, during his campaign for a second presidential term, Obama focused on grassroots initiatives. Celebrities such as Anna Wintour and Sarah Jessica Parker aided the president's campaign by hosting fund-raising events.

"I guarantee you, we will move this country forward," Obama stated in June 2012, at a campaign event in Maryland. "We will finish what we started. And we'll remind the world just why it is the United States of America is the greatest nation on Earth."

In the 2012 election, Obama faced Republican opponent Mitt Romney and Romney's vice-presidential running mate, U.S. Representative Paul Ryan. On the evening of November 6, 2012, Obama was announced the winner of the election, gaining a second four-year term as president. Early election results indicated a close race. By midnight on Election Day, however, Obama had received more than 270 electoral votes—the number of votes required to win a U.S. presidential election; later results showed that the president had won nearly 60 percent of the electoral vote, as well as the popular vote by more than 1 million ballots.

Nearly one month after President Obama's re-election, the nation endured one of its most tragic school shootings to date: On December 14, 2012, 20 children and six adult workers were shot to death at the Sandy Hook Elementary School in Newtown, Connecticut. Two days after the attack, Obama delivered a speech at an interfaith vigil for the victims in Newtown, discussing a need for change in order to make schools safer, and alluding to implementing stricter gun control.
