ATLANTA -- Cortez Carter, one of the highest-ranking officials at Atlanta Hartsfield-Jackson International Airport, is facing a city hall investigation.

A city hall spokeswoman told 11Alive News that it deals with concerns that his wife's company does business with an airport subcontractor at Reagan National Airport in Washington, D.C.

For now, Carter has been placed on administrative leave. Atlanta officials say they need to determine whether Carter, the deputy general manager at Hartsfield-Jackson, has violated any city laws or rules due to his wife's business dealings.

"We take this matter very seriously. We want to ensure the public has trust in their government, and even the appearance of impropriety erodes the public's trust," the city statement read. "If any violations of protocols, ordinances or policies are found to have taken place, we will address the situation immediately and without hesitation."
