The Senate passed the new North American trade pact on Thursday, helping President Trump fulfill a 2016 campaign promise.
The U.S.-Mexico-Canada Agreement is an update to the original NAFTA with Mexico and Canada.
The USMCA tightens rules for car manufacturing and worker earnings. It also increases American access to Canadian dairy markets and updates digital trade rules.
The USMCA will now be sent to Trump's desk. It was passed by Mexico in December, but will not go into effect until Canada approves the pact. Canada is expected to vote on the deal in the coming weeks.
