Eleanor Jean Hill (born December 19, 1950) served as Inspector General for the United States Department of Defense under President Bill Clinton.

[2] She was awarded the Department of Defense Distinguished Service Medal by Secretary William Perry and the Bronze Palm to the Department of Defense Medal for Distinguished Public Service by Secretary William Cohen.

According to leaked diplomatic cable of February 2010, the FBI has investigated another suspect, Mohammed al-Mansoori, who had associated with three Qatari citizens who had flown from Washington to London on the eve of the attacks, after allegedly surveying the World Trade Center and the White House.

U.S. law enforcement officials said that the information about the four men was "just one of many leads that were thoroughly investigated at the time and never led to terrorism charges".

Eleanor Hill, the former staff director for the congressional joint inquiry on the September 11 attacks, said the cable reinforces questions about the thoroughness of the FBI's investigation.
