When Barack Obama became the forty-fourth president of the United States in 2009, he appointed Norman Eisen, a “special counsel for ethics and government,” to ensure that he violated no prohibitions on conflicts of interest. Before he was replaced in 2011, Eisen, later an ambassador to the Czech Republic and a lawyer who specialized in cases involving fraud, addressed a wide range of questions, including such matters as whether President Obama, a basketball fan, could accept tickets to see the Washington Wizards or the Georgetown Hoyas play.
When Obama was awarded the Nobel Peace Prize, he sought a formal opinion from the Justice Department's Office of Legal Counsel on whether he could accept the award without violating a constitutional prohibition on the president or any other federal officer accepting “emoluments,” essentially any payment or benefit, from a foreign state. (The office concluded that he could, only because the Nobel Prize Committee is a private entity with no foreign government involvement.) Like every president to precede him in the last four decades, President Obama placed all his investments in a blind trust, so that he would be unaware of his interests and therefore free of conflicts of interest with respect to the many decisions he might make that could affect his own personal wealth. President Obama, again following the precedents of his predecessors, also released his tax returns, both during his campaign for office and as president. Obama, in short, was punctilious about ethics, and his administration was almost entirely free of ethics scandals.
