The US-Mexico-Canada Agreement (USMCA) is set to replace the 1994 North American Free Trade Agreement (Nafta), which Mr Trump and Democrats have blamed for speeding the decline of US manufacturing. Negotiators from the US, Mexico and Canada reached a deal past year, but it needed to be approved by lawmakers in the three countries to move forward.
An agreement today would allow Lighthizer to modify the implementation bill that CUSMA proponents still hope could be brought to the floor of the U.S. House of Representatives before its Christmas break, amid impeachment proceedings and ahead of the presidential primary season.
US Trade Representative Robert Lighthizer said the new additions to the United States-Mexico-Canada Agreement (USMCA) - which notably toughened the deal's labor enforcement provisions - made it the "best trade agreement in history".
Mexico had ratified the deal in June while the Canadian government has said it is waiting to ratify the agreement at the same time as the United States.
US House Speaker Nancy Pelosi - the key opposition Democrat needed to move the agreement forward - and American labor unions on Tuesday gave their blessing to the deal, which they said now included improved labor standards.
Mr. Trump spoke to Canadian Prime Minister Justin Trudeau on Monday to discuss finalizing the deal, according to the White House.
But the trade deal highlighted how much more Trump could have accomplished "had he stuck to the national agenda", Gergen said.
For Democrats, the deal serves as a retort to Trump's and Republicans' assertions that their only agenda was pursuing his impeachment.
The new deal is sure to stoke anger in some circles, with the Canadian and USA aluminum and automotive industries in particular angry that Mexico had not agreed to tighten the definition of what constitutes North American aluminum like it did with steel.
"I'm hearing very good things".
House Ways and Means Committee Chairman Richard Neal told reporters he was "delighted" that a deal was close at hand, and was convinced it would offer better protection for workers.
Pelosi said the reworked trade agreement has provisions that are better for the environment and for labor.
"I think Canada should be especially pleased with [the new agreement]", said Bruce Heyman, former United States ambassador to Canada, in an interview with BNN Bloomberg Tuesday. "Importantly, we will finally end our Country's worst Trade Deal, NAFTA!"
The major AFL-CIO union also said Tuesday it was endorsing the agreement after working with lawmakers and Team Trump negotiators to make changes to the proposal Trump first introduced in 2017. We got the agreement, we're going with it.
In another missive, he wrote: "Looking like very good Democrat support for USMCA". It will also protect biologic drugs from being imitated by other manufacturers for at least 10 years, which Democrats claim will help lower drug prices.
He said it would also eliminate "special carve outs for corporations like the giveaway to Big Pharma in the administration's initial proposal and loopholes created to make it harder to prosecute labor violations".
"We ate their lunch", Pelosi told her Democratic colleagues in a closed-door meeting, according to an aide in the room. Since then, Democrats and the Donald Trump administration have been locked in tense negotiations.
