Investigators looking into the travel of a senior General Services Administration official have examined a trip he made to Atlanta last November for an international corporate real estate conference at the Georgia World Congress Center.

Jeff Neely, who took the Fifth Amendment before Congress this week and refused to answer any questions from lawmakers, spent $1,800 on his trip to Atlanta for the CoreNet Global Summit, which was held November 6-8, 2011.

Neely may be best known by the photograph taken of him sitting in a hot tub in his Las Vegas hotel suite, with two big glasses of wine in the picture.

That 2010 Vegas conference, which was organized by Neely, ran up a government tab of over $822,000 and has Congress and GSA investigators looking for other examples of bureaucratic largesse.

"California, Atlanta, Hawaii, Guam, Saipan," said Rep. John Mica (R-FL), ticking off the list of destinations visited by Neely, all of which have drawn investigative scrutiny in recent weeks.

Neely was one of ten GSA employees who came to last year's conference in Atlanta, billed as "the world’s leading association for corporate real estate (CRE) and workplace professionals, service providers and economic developers."

The GSA employees included David Foley, a deputy GSA Administrator who was recently placed on administrative leave for his role in the Vegas conference.

Foley was caught on a video joking about the excess spending by GSA conference organizers, something he apologized for in hearings this week.

Neely has been a regular at CoreNet Summits through the years, leading a GSA delegation in 2007 to accept an award for "Achievement in the category of Public Sector and Government" for a government high-rise complex in San Francisco.

That award was made at an event in Denver.

Aides on the U.S. House Transportation Committee were unable to say if anything suspicious had been found about Neely's trip to Atlanta last year, but lawmakers made clear it was getting an official review.

"A five day trip to Atlanta to attend a non-training conference," said Rep. Jeff Denham (R-CA) with an air of disgust in his voice.

If going to these meetings weren't good enough for Foley, then GOP lawmakers might want to look at the next CoreNet Global Summit, scheduled for later this month in San Diego.

Eight GSA employees are on the list for that conference, including Foley - who certainly won't be going on Uncle Sam's tab, as he remains on administrative leave pending further investigation.

The Atlanta conference also included other federal employees, as three workers with real estate ties attended from the State Department.
