Fisher was chief administrative officer at the Government Accountability Office, the investigative arm of Congress that audits government programs. Fisher was in charge of all of the office's internal operations, including its budget and financial management.
Before that, Fisher led a Defense Department effort beginning in 2005 to overhaul that agency's business operations.

Werfel said in a written statement that Fisher will evaluate the agency's operations "to mitigate risks and improve internal controls necessary for restoring the integrity of IRS operations." He said Fisher will recommend any policy changes he feels are needed.
