U.S. Senate on Wednesday approved the so-called fast-track trade legislation, and the bill will be sent to the White House for signing.

The 60 to 38 Senate vote capped weeks of fighting over the trade bill and gave a big push for the Obama administration's trade agenda.

The fast-track legislation, formally known as Trade Promotion Authority (TPA), empowers the president to negotiate trade deals and then present them to Congress for up-or-down votes, with no amendments allowed.

With the legislation passed by the full Congress, it will give U.S. trading partners the confidence they need to put their best offers on the table and help the Obama administration conclude the ongoing Trans-Pacific Partnership (TPP) free trade talks, which are nearing completion after more than five years of negotiations.

The Senate is scheduled to vote later Wednesday to end debate on and pass a trailer bill that includes trade adjustment assistance (TAA), which provides relief for U.S. workers who lose their jobs as a result of U.S. trade deals with other countries.
