Bush suddenly started avoiding Foley in Sept. 2004, after months of using Foley to help Bush's re-election campaign. What did Bush find out?

Why did the White House suddenly decide two years ago that Foley was too hot to handle? And even more interesting, why did Foley reach out to Jeb Bush about something he needed his advice on right about the time Foley's creepy emails became known amonst Republicans on the Hill in late 2005? Did Foley and Jeb Bush talk about the sdandal a year ago? Did the White House know something two years ago?
