Media question, in case anyone knows, on the streams that come

[liveoaktx]

when someone from the White House speaks. Noticed the other day that Democracy Now had an excerpt of something from Bush that didn't have Cspan's logo on it, and I have heard before that on some press conference, there's a "Pool" feed that goes out- do you suppose it's possible to access that directly by asking about it?
As another example, I can go to CBSNEWS.com and watch live speeches as they occur over a CBS news feed. It's refreshing, because there aren't any commercials or blah-blahing talking heads saying what the speaker is saying but the real thing, firsthand. That may be CBS specifically setting it up as a convenience for their consumers but you know how the WH provides speeches for people-on what basis?
