"It's the President...of the United States...of America..."
Anthony DiNozzo to his boss, NCIS Special Agent Leroy Jethro Gibbs.
Barack Hussein Obama II is the 44th President of the United States and also the first African American president, representing the Democratic Party, succeeding George Walker Bush.
On May 1st, 2011, Obama gave authorization to a strike mission that killed al-Qaeda terrorist leader Osama bin Ladin, whom NCIS, along with every other federal agency, had been looking for since the 1993 World Trade Center bombing, the 1996 Khobar Towers bombing, the 1998 African embassy bombings, the USS Cole bombing, and the 9/11 attacks.
In May 2012, after terrorist Harper Dearing had attacked the NCIS Building and also the Navy Yard, Obama contacted SECNAV Clayton Jarvis with Obama telling Jarvis to proceed with "extreme prejudice".
In September 2013, Jarvis along with multiple others, were killed in a hotel bombing. The White House demanded answers by any means necessary from NCIS. President Obama later personally called Clayton's wife to offer his condolences.
In September 2014, Obama tried to call Edward Wallace, not knowing he had been murdered. The blocked call was answered by NCIS Special Agent Anthony DiNozzo. Asking each other who the other was, DiNozzo told him to stop being a "wiseass" and identify himself. Obama did and DiNozzo, shocked at realizing he had just cursed at the President, immediately tried to hand the phone off to his boss, Leroy Jethro Gibbs. Gibbs and NCIS directer Leon Vance both later met with the President, giving him a report on Wallace's death.
