Obama has also handled a number of military and security issues during his presidency. In 2011, he helped repeal the military policy known as Dont Ask, Dont 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 Obamas health care law stating that while the mandate is unconstitutional, according to the Constitutions commerce clause, it falls within Congress constitutional power to tax.
