Which individual heads the Department of the Interior?

The head of the Department of the Interior is the Secretary of the Interior, who oversees the management and conservation of federal land and natural resources, among other responsibilities. Kenneth Salazar served as the Secretary of the Interior from 2009 to 2013 under President Barack Obama, making him a well-known figure in this position during that time. This includes overseeing national parks, wildlife refuges, and the Bureau of Indian Affairs, as well as addressing issues related to energy development and environmental protection.

The other individuals listed do not hold this position. Eric H. Holder, Jr. served as Attorney General, Arne Duncan was Secretary of Education, and Ray LaHood was Secretary of Transportation. Each of their roles pertains to different departments, which are separate from the responsibilities of the Department of the Interior. This distinction reinforces that Kenneth Salazar is indeed the correct individual heading the Department of the Interior during his term.
