On November 11, 2011, Oscar Ramiro Ortega-Hernandez, an unemployed 21-year-old man, fired multiple shots at the White House using a semi-automatic rifle. At least seven bullets hit the second floor. Neither the President Barack Obama nor First Lady Michelle Obama were home at the time; the president was not in Washington, D.C., having been on a trip abroad. However, the couple's youngest daughter, Sasha, and the first lady's mother, Marian Shields Robinson, were in the White House. No one was injured. It took four days for the Secret Service to realize that bullets had struck the White House. Michelle Obama learned of the shooting from an usher, then summoned Mark J. Sullivan, director of the Secret Service, to find out why the first family had not been informed.
