Sen. Elizabeth Warren is asking progressive activists to join her in fighting the Trans-Pacific Partnership throughout the summer and fall, releasing a five-minute video Thursday blasting the pact as part of a "rigged system" that benefits corporations over American workers.

"We're going to need your voices now more than ever," Warren (D-Mass.) says at the end of the video, which was released by CREDO, a liberal activist group that is fighting the TPP and worked against trade promotion authority legislation last year. The Massachusetts senator said she was counting on the organization's members "to help [her] fight to stop the TPP over the next few months."


Warren, who has been floated as a potential vice presidential pick for Democrat Hillary Clinton, highlights the Investor-State Dispute Settlement clause of the trade deal in the video, calling it a key provision that benefits big business while weakening public safety regulations.

"It'll be open season on laws that make people safer but cut into corporate profits," she says.

Warren notes that because of fast track, Congress will have to vote TPP "straight up or down — no amendments, no chance to strip out things like ISDS," which is why she says she's reaching out to activists for help.

"America shouldn't be signing lousy trade deals, period," she says.
