a "tea party movement" started during obama's presidency. this group opposes obama's health care plan and other policies they see as "big government." due to the recession, the tea party and a dislike of what obama did, republicans won a large number of house and senate seats in the 2010 election. in 2011, tea party members of congress almost shut down the government and sent the u.s. into default (not being able to pay people the government owes money). a few months later, many young people protested against organized and concentrated wealth during the occupy movement. in 2012, obama was reelected to a second term. following reelection, obama faced major obstruction from congressional republicans. this polarization in the political atmosphere and the media, lead to events such as the 2013 federal government shutdown and the stalling of obama's supreme court pick, judge merrick garland to replace justice antonio scalia. in 2014, republicans took control of both houses of congress, further adding to the gridlock. in foreign policy, president obama helped crafted the paris climate agreement, a major global commitment to fighting "climate change". he also forged the iran nuclear agreement, which was widely seen as an enormous failure. he also opened relations with cuba for the first time in fifty years.
