Who said what to whom?

My sister told me this evening that she had heard some new info on the story about the Canadian leak that an Obama aide had supposedly told Canadian diplomats not to take his stance on NAFTA seriously. She had heard that it was actually a Clinton aide that had made the statement originally. I decided to see what I could find about it on the internet and I came across this article from Canada.com: Canada's NAFTA leak is regrettable: U.S. envoy. From what I can tell, this would seem to back up that position, if I'm reading it correctly.

Canadian media reports said on Thursday that the furor was triggered by private remarks that Ian Brodie, Harper's chief of staff, made to the CTV Television network last week about Clinton's criticism of NAFTA.

They said Brodie revealed someone from the Clinton campaign was "telling the embassy to take it with a grain of salt." CTV investigated the remarks and then ran a story focusing on Obama, saying his adviser had privately told Canadian diplomats that a promise to reopen NAFTA was solely aimed at winning votes in the Ohio primary.

I'm not sure if that is saying that both campaigns have supposedly said the same thing or that it was actually an act by the Clinton campaign that got attributed to the Obama campaign. If it is true that the real story is the reverse of what voters were told, I would think that any momentum Hillary gained from Tuesday's primaries would instantly evaporate.
