Congressional officials say the House will attempt as early as Thursday to revive trade legislation sought by President Barack Obama and blocked last week in a revolt by union-backed Democrats.

The officials say the vote would come on a stand-alone measure that would allow Congress to approve or reject future global trade deals, but not change them.

The Obama administration is seeking the authority as it works to wrap up a deal with 11 Pacific Rim nations.

A provision to renew a program of assistance for workers who lose their jobs because of imports would become part of a separate bill.

The officials stress that plans for a Thursday vote are not yet final.

The officials spoke on condition of anonymity to avoid pre-empting any formal announcement.
