I saw it on a press conference yesterday, on FOx News. SOrry, I don't have anything else as a source.
I'll see what I can find.

This was apparently in a report Ashcroft gave to Congess in June? of 2004. The people were not named in the report. I can't find the report itself.
If so, this is the first example of the Patriot Act being used in this manner. Maybe someone can find a copy of the report. No name, just that is is 29 pages long is all I could get on the fly.
