Interior Sec. Salazar will stay behind from State of the Union

Interior Secretary Ken Salazar will not attend the State of the Union at the Capitol Tuesday night as he serves as the "designated survivor" for the administration.

The Washington Post reported that Salazar will skip the speech as a safety measure in the case of a event that would incapacitate other members of the administration, including President Obama, who will be in attendance.

"Designated survivors" have been picked to not attend the speech for decades. Last year, Housing and Urban Development Secretary Shaun Donovan stayed behind for Obama's first State of the Union.
