From The Washington Post:

A bi-partisan group of Senators is questioning why the White House has not nominated a new Transportation Security Administration head more than three months after the agency’s previous leader announced he was stepping down, saying that TSA should be a greater priority at a time of heightened concern about terrorist threats to the homeland. In a letter sent to President Obama late Monday, the Senators – led by John Thune (R-S.D.), chairman of the Committee on Commerce, Science, and Transportation – urged the President to “prioritize the formal nomination of a qualified, experienced, and dedicated individual” to serve as TSA administrator.
