Retiring Defense Secretary Leon Panetta told NBC he was frustrated with last week's confirmation hearing. Panetta said Senate leaders ignored questions ranging from looming budget cuts to evolving terrorist threats in the Middle East.

Hagel received overwhelming support from former U.S. secretaries of defense and national security advisers before last week's hearing. Despite a tough nomination hearing, he's expected to be confirmed as secretary of defense.
