The Houston Chronicle reports (http://bit.ly/XUQlb1) that a spokesman for former President George H.W. Bush declined to comment on a report on The Smoking Gun website detailing the alleged security breach.
Bush spokesman Jim McGrath told the Chronicle the matter is "under criminal investigation." McGrath did not immediately respond to messages seeking comment by The Associated Press early Friday.
The Smoking Gun says the hacker went by the online moniker "Guccifer," a word plastered across the leaked photos in translucent, neon blue print.
The website quotes "Guccifer" as describing himself as a veteran hacker who has long been in the government's sights.
