Chris Hayes nearly stumps Sen. Bernie Sanders with this question about why President Obama is so eager to pass the Trans-Pacific Partnership: "Is the President wrong? Is he being deceitful? How -- what is your account of why President Barack Obama wants this deal so badly?"



"I’m not going to psychoanalyze Barack Obama," responds Sanders. "On this issue, he's wrong. Bill Clinton was wrong on NAFTA."





SEN. BERNIE SANDERS (D), PRESIDENTIAL CANDIDATE: Well, you stop it by organizing the American people. I think most of whom understand that our previous trade agreements, of which TPP is just another one, have been disastrous for the middle class and working families. They've been written by corporate America. The result is that since 2001, Chris, we have lost 60,000 factories in America, millions of decent paying jobs, a lot of it attributable to disastrous trade policies. Truth is, the American worker should not have to compete against people all over the world who are making pennies an hour.



HAYES: Here's the question I think a lot of folks who are watching this are going to have because what’s going to happen is the President - like he did for the passage of fast track - is going to go around and he’s going to say, look, this is in the best interests of American workers and you have my word on this because I am someone who cares about American workers and cares about growing the middle class and share the same values as you.



Is the President wrong? Is he being deceitful? How -- what is your account of why President Barack Obama wants this deal so badly?



SANDERS: I’m not going to psychoanalyze Barack Obama. I worked with him on that issue. He's a friend. On this issue, he's wrong. Bill Clinton was wrong on NAFTA.



Republicans were wrong on PNTR with China.



You know, I think if you look at the history of trade agreements, Chris, what you find, they are written by Wall Street. They are written by corporate America. They're written by the drug companies, written by -- they have been, in my view, a disaster for the American worker. And now the President differs, and he will tell you why he differs.



On this issue, I think he is wrong. I think virtually every union in this country that virtually all of them oppose this agreement.



Elizabeth Warren and I will help lead the effort to defeat it.
