President Barack Obama took on Elizabeth Warren and the far-left wing of the Democratic Party Tuesday night in an effort to push the Trans-Pacific Partnership forward.

In an interview with MSNBC’s Chris Matthews, Obama fired back at Warren, who has been leading the charge against the TPP, saying she’s “wrong” on the issue at hand.

Obama told Matthews that everything he does is “focused” on getting the middle class a fair deal, adding that this deal is indeed good for the middle class.

“I love Elizabeth. We’re allies on a whole host of issues. But she’s wrong on this,” Obama told the MSNBC host. “When you hear folks make a lot of suggestions about how bad this trade deal is, when you dig into the facts, they are wrong,”

“If we want to compete and create jobs here in the United States we’ve got to be there, and the fastest growing, most populace region in the world is in the Asia-Pacific region,” Obama added. “So, we’ve pulled together 11 countries to come up with a high standard, an enforceable trade provision that has unprecedented labor standards, unprecedented environmental standards, fixes a lot of the problems that you had in things like NAFTA and, ultimately, I would not be putting this forward if I was not absolutely certain that this was going to be good for American workers.”

“Now, understandably, folks in labor and some progressives are suspicious generally because of the experiences they saw in the past,” Obama conceded. “But my point is don’t fight the last war. Wait and see what we actually have in this deal before you make those judgements because what I know is if we are going to succeed as an economy, where already about 11 million of the high paying jobs in the United States are directly related to exports overseas. And it’s not just big business. It’s small businesses like are represented around this table, then we’ve got to be able to craft the kinds of trade deals I’m talking about.”
