Input: Question: Who is older between the Pennsylvania Congressman and the US President? Passage:The United States Navy dog handler hazing scandal was a pattern of misconduct engaged in by members of the United States Navy at Naval Support Activity Bahrain between 2004 and 2006. Naval investigators documented nearly 100 incidents of abuse committed against several members of a Military Working Dog (MWD) unit stationed at the United States military base at Juffair. Documented incidents of abuse include racial intimidation, sexual harassment, physical abuse and anti-gay harassment. One sailor, Master-At-Arms 3rd Class Joseph Rocha, suffered post-traumatic stress disorder because of his abuse at the hands of fellow sailors, and he alleges that another sailor committed suicide because of her treatment. The Navy investigated the allegations in 2007 and documented the abuse, but took little substantive action. However, Pennsylvania Congressman Joe Sestak, a former Vice Admiral, demanded a new examination of the report's findings which led to the disciplining of Rocha's former superior, Chief Petty Officer Michael Toussaint (later Senior Chief Petty Officer). The scandal came to widespread public attention as United States President Barack Obama faced increased pressure to repeal the military's gay-exclusionary policy known as "don't ask, don't tell" (DADT).
