WASHINGTON (CNN) - More than seven months into office, President Obama still has a number of top posts to fill, which one expert said could be hurting the nation's security.
An analysis by the White House Transition Project - a nonprofit organization tracking administrations - showed that 210 days into his administration, Obama had nominated candidates for 243 of the 385 jobs requiring Senate confirmation.
The Senate has confirmed 193 but still has a backlog of candidates needing to be examined.
Some of the top jobs open include assistant secretary of state for nonproliferation, and the directors of the Agency for International Development, Customs and Border Protection, Drug Enforcement Administration, and the Bureau of Alcohol, Tobacco, Firearms and Explosives.
David Lewis, a professor at Vanderbilt University, said the vacancies in key posts might be hurting the nation's security.
