Sen. Elizabeth Warren, D-Mass., who was recently elevated to a Democratic leadership role, urged her colleagues to vote against the measure.

Warren’s criticism centered on changes to Dodd-Frank, a law that some Democrats view as off limits in the spending package. Speaker John Boehner, R-Ohio, pushed back, noting that former Financial Services Chairman Barney Frank, D-Mass., and the committee’s current ranking member, Rep. Maxine Waters, D-Calif., supported the same provision.

Warren isn’t alone. Other lawmakers, including Rep. Chris Van Hollen, D-Md., ranking member of the House Budget Committee, criticized the bill.

At least three prominent progressive organizations—AFL-CIO, Common Cause and Teamsters—also urged lawmakers to vote against the $1.1. trillion spending package that totals more than 1,600 pages.

Without action from Congress, government funding is set to run out Friday. House Republicans need 218 votes to pass the spending bill and were reportedly counting on Democrats to account for conservative defections.
