Atlanta's mayor says it was an honest mistake--the city's purchase of a first-class plane ticket for her husband.

In an exclusive interview Mayor Keisha Lance Bottoms tells WSB’s Pete Combs that she was the one who discovered the city had wrongly paid for her husband's ticket to Minneapolis back in February. She stated that she thought the trip had been charged to her personal credit card.

“When I returned from the trip, I immediately realized my credit card had not been used.”

That's when the mayor says she alerted her staff and wrote a check to pay back the $1434.42 cost of that ticket. Bottoms says she never asked the city to pay for her husband's travel and the incident has prompted her to start rethinking the way credit cards are used in the mayor's office.
