More on Obama's San Antonio Presser

Reporting from TIME's Jay Newton-Small:

Obama, in what was one of the most heated avails that I've seen so far in his campaign, took two questions on the NAFTA imbroglio. He defended his advisor, Austan Goolsbee, saying the conversation Goolsbee had was taken out of context and never did Goolsbee imagine he was representing the campaign when he made them. Obama was confident that Goolsbee simply parroted Obama's own position that NAFTA needs to be rewritten and nothing else. “The Canadian Embassy in Chicago contacted one of my advisors, Austan Goolsbee, and the Canadian Embassy has confirmed that he said exactly what I've said on the campaign trail” on NAFTA, Obama told reporters. “This notion that Senator Clinton is peddling that somehow there was contradictions or winks and nods has been disputed by all parties involved. What's not disputed is that Sen. Clinton and her husband championed NAFTA.”

“Just understand the context,” Obama said when asked about it a second time. “Nobody reached to the Canadians to try and assure them of anything. They reached out to Mr. Goolsbee” who thought he was having “a casual conversation.”

“The terms of NAFTA have to be altered,” Obama said, noting he was criticized for his position on NAFTA by the Chicago Tribune during his 2004 Senate run. “I have said repeatedly that I believe that NAFTA needs to be modified.”

Obama also took questions on the opening of the Rezko trial (he retold the same bonehead story he's been saying for months), the importance of winning Texas (Wisconsin, Illinois and Washington are big states in his book), veterans (he supports them) and whether he'd negotiation with Hamas (no, they aren't a head of state).
