In the revision of 7:53 2 Jul 2003, we read:
Friedrich-Wilhelm Graefe zu Baringdorf (Grune party), Vicepresident of the Landwirtschaftsausschuss (committee of agriculture?) of the European Commission said on the 1.July.03: "In America 55% of the consumers are against GM food and 90% in favor of a clear labelling. The Bush government is ignoring the demand of his own people."
A little rough, but the point of view is attributed. It's completely uncontroversial, I suppose, that Graefe did say such a thing, and it's just the sort of thing that we expect Green Party politicians to say.
But in revision 8:03 2 Jul 2003, we see this new line appear: "Also American consumer demand that, but the Bush administration is ignoring that fact." That's written as an assertion _by Wikipedia_.
This is a blatantly political statement, and whether or not it is actually true is irrelevant. (I personally think it is preposterous, but that's the nature of finding POV claims, I suppose -- the ones that stick out for us are the ones that we find particularly silly.)
Citing a politician from the German Green Party saying such a thing is wonderful. The cite itself gives the reader sufficient context to evaluate the claim, and in any event _Wikipedia_ is not making a political claim at all.
It would likely be helpful to have a balancing quote from a scientist, of course, but it isn't strictly speaking necessary.
What *is* necessary is that Wikipedia avoid making claims of this sort.
