Just passed by a vote of 60-38:

The Senate has handed President Barack Obama a major victory by approving "fast track" authority to negotiate trade agreements in Asia and elsewhere.

The 60-to-38 vote on Wednesday clears the way for Obama to seek final language on a trade agreement with Japan and 10 other Pacific-rim nations. Congress can ratify or reject such agreements but not change them.

The Senate granted Obama the same fast-track authority that previous presidents have enjoyed. The GOP-controlled House passed it earlier with help from 28 Democrats.
