New information raises even more questions about Nashville Mayor Megan Barry's need for police security -- security that you paid for.

It follows the mayor's admission last week of a two-year affair with the head of her security detail.

Late Monday afternoon, the mayor's office released new details about her travel and her use of security, in hopes of convincing the public that she did not abuse taxpayer money.

The documents show that, during the first year of her administration, Barry traveled alone to Boston, New York, Washington D.C., Oklahoma City, and Phoenix.

There were other trips -- to Los Angeles, for example -- where she traveled with other staff members, but no security.

Her first out-of-state trip with Forrest -- as well as other city officials -- was to Minneapolis in April 2016.

But in 2017, for the first time, Barry and Forrest started traveling alone together, when they took nine trips, including to Athens, Greece and Paris, France.

In a statement, the mayor's office cited security concerns.

"This was based on the recommendations of the Police Department that Mayor Barry have police detail on all official business trips, increases in terrorist attacks and mass shootings both domestic and international, and because we had an opportunity to learn what worked best in terms of logistics for travel," the statement continued.

Meanwhile, we're learning more about Rob Forrest's overtime that you paid for.

It turns out, the time he spent with Mayor Barry made him the second highest-paid person in the Metro Police Department.

In fiscal year 2017, Chief Steve Anderson made the most, earning $209,806, according to Metro government records.

Forrest was second. With overtime, he got paid $158,527.

That was more than the head of internal affairs, who earned $149,377, and the three deputy chiefs. They each made $147,481.

Meanwhile, the TBI investigation continues.

Metro police spokesperson Don Aaron confirms that Sergeant Forrest police-issued smartphone has now been turned over to the TBI.

Presumably, investigators will be looking for text messages and other evidence.

Still, the mayor's office insisted there was no misuse of funds.

“As the Mayor has acknowledged, it was inappropriate to start and continue this relationship, but we believe that any and all expenses incurred by either Sgt. Forrest or Mayor Barry were in the course of normal business," the statement said.
