The attack of an American diplomatic compound in Benghazi, Libya in 2012, the debate over the Affordable Care Act and the operation of the Guantanamo Bay Detention Camp are considered to be controversial, perhaps scandalous, topics during President Obama's administration. For the Benghazi situation, critics accused the president of a cover-up. The Affordable Care Act has been a polarizing legislative move. The controversial Guantanamo Bay prison remains open, as of 2015.
Four Americans, including the U.S. Ambassador to Libya, were killed in the Benghazi attack. Soon after, questions arose of if the administration had prior knowledge of the risk of the attack. Obama's then Secretary of State Hillary Clinton was accused of failing to respond sufficiently to warnings of the attack. Some questioned if the president, heading into reelection, misled the American public about the perpetrators and motives of the attack.
One of the president's key pieces of legislation, the Affordable Care Act, sometimes referred to as "Obamacare," has been repeatedly challenged by critics. Supporters of the insurance mandate feel it provides much-needed health insurance coverage to otherwise uninsured Americans; opponents view it as an overreach of federal government into the right of private citizens to make their own decisions about health care. Questions of the constitutionality of requiring citizens to obtain health insurance led to legislative attempts to overturn the law and a Supreme Court ruling.
At the outset of his presidency in 2008, Obama vowed he would close the prison at Guantanamo Bay, Cuba. Charges of human rights violations, including torture of prisoners, were abundant and served to embarrass the president with heightened public awareness that his promise to close the prison did not materialize.
