Massachusetts Congressman Richie Neal says he’s likely to vote against fast- track trade legislation supported by President Obama.

The measure, largely supported by Republicans, would have Congress vote up or down – without amendments – on a forthcoming Trans Pacific Partnership, or TPP, trade agreement. But Neal, a Springfield Democrat, says he has serious concerns about labor standards and other issues. And he’s not comfortable giving up authority at the outset on an uncompleted agreement.

“If you had a chance to see what the final TPP product was going to be, then you perhaps would vote to grant the president trade promotion authority. The problem is that you’re being asked to grant trade promotion authority and then have a chance to see finally what TPP would look like,” says Neal.

Fellow congressman Joe Kennedy, who was visiting the area with Neal, says he’s definitely voting against fast-track authority.
