When former Texas Gov. Rick Perry faces the Senate Committee on Energy and Natural Resources for his confirmation hearing on Thursday, his first test could be whether he remembers the name of the agency he's been picked to head.

The Department of Energy (DOE) is one of three agencies Perry proposed eliminating when he was running for president in 2011. During a debate, he successfully listed the Department of Commerce and the Department of Education. But he couldn't bring to mind the name of the third agency — the Energy Department.
