Below we noted that The New York Observer had gotten Austan Goolsbee to deny that he'd had any conversations with any Canadian official about whether Obama's NAFTA stump talk was mere "campaign rhetoric," as Canada TV reported.

“It is a totally inaccurate story,” Goolsbee told The Observer “I did not call these people and I direct you to the press office.”

But ABC News reached Goolsbee, too, and they had a different conversation:

ABC News' Jennifer Parker spoke to Goolsbee, a University of Chicago economics professor, Thursday who would not confirm or deny that he had a conversation with Georges Rioux, the Canadian Consulate General in Chicago. Rioux, in meetings this week in Ottawa, would also neither confirm nor deny any conversation took place. Both men did say that they know each other.

So, according to ABC, neither of those two men would confirm or deny whether they talked. The Obama campaign has a statement out today that doesn't explicitly mention Goolsbee, but said the story is "not true," and added that "no one at any level of our campaign, at any point, anywhere, who said or otherwise implied Obama was backing away from his consistent position on trade."
