The Air Force has determined that Booz Allen Hamilton is not responsible for the disclosure of government secrets by former employee Edward Snowden a spokesman for the service said Thursday.

“At this time, we have no indication of any wrongdoing on the part of the Booz Allen Hamilton corporation,” said Lt. Col. John Dorrian, an Air Force spokesman.

McLean-based Booz Allen has faced scrutiny since the recent disclosure that Snowden accessed information on classified National Security Agency programs while working for the contractor.

The company has faced allegations of improper contracting behavior in the past, including last year when the Air Force temporarily suspended a division of the company. Booz Allen had hired a Pentagon official who brought “non-public information,” which was shared with the company to help it win a contract, the Air Force found.

The Air Force lifted Booz Allen’s temporary suspension in April of last year after the firm agreed to implement ethical and other reforms as well as pay $65,000. Under the agreement reached in that case, Booz Allen was required to report the Snowden incident to the Air Force.

“The Air Force’s suspending and disbarring official is monitoring Booz Allen’s handling of the Snowden” case, Dorrian said. So far, the Air Force has found that “they’re meeting the obligations that they’ve agreed to in the ­administrative agreement.”

The Air Force’s conclusion was first reported by Reuters.

James Fisher, a Booz Allen spokesman, said in a statement that the company is “pleased to see comments from the U.S. Air Force reflecting support of our efforts to maintain high ethical standards, and finding no evidence of inappropriate actions related to the Edward Snowden incident.

“We are participating fully in the government’s investigation of his actions and out of respect for that process, currently have no additional information to provide about the substance of the allegations related to his conduct,” Fisher added.

Federal contracts constituted 99 percent of the firm’s $5.8 billion in revenue last year. The consulting company is majority-owned by Carlyle Group, a local private-
equity company.

It is unclear whether Booz Allen’s behavior is under investigation by any other government agency. But some in Congress have questioned whether the case demonstrates that the government, including intelligence agencies, has become too dependent on contractors for sensitive tasks.
