A pre-election "action plan" released by President Donald Trump listed a plan to renegotiate or withdraw from the North American Free Trade Agreement as the top strategy it will pursue to protect American jobs.
But it could be quite some time before a new version of that deal is formally set in motion, according to trade experts.
To renegotiate NAFTA, under a law passed in 2015, the White House must open an official 90-day negotiating window with Congress, during which time the legislative and executive branches will debate how the deal should be changed. That hasn't happened yet, according to congressional aides with knowledge of the process.
The White House is, however, pursuing informal negotiations, as evidenced by a meeting with leadership from the Senate Finance Committee and House Ways & Means Committee in early February. Press secretary Sean Spicer called the group — which included chief strategist Steve Bannon, presidential adviser Jared Kushner and the then-unconfirmed Commerce Secretary Wilbur Ross — an "all-star team" that would "chart the future of U.S. trade policy."
"The fact that the President met with Congressional leaders on Feb. 2 and discussed NAFTA renegotiation does not mean the U.S. clock has started," according to Ambassador Carla Hills, the primary NAFTA negotiator as U.S. Trade Representative under George H.W. Bush.
A senior Trump administration official called that meeting informal, saying the White House would pursue substantive changes in the deal through "proper channels." In the meantime, aides for the House Ways & Means committee and the Senate Finance committee — the groups with jurisdiction to rework trade agreements — told CNBC they had not received communication from the White House to do so before recess began this week.
The purpose of the 90-day period is to allow the Administration and Congress to "develop common goals," according to Ambassador Miriam Sapiro, a former deputy U.S. trade representative under President Barack Obama who today is with public relations firm Finsbury.
Traditionally, the role of liaison between the White House and Congress would be served by the U.S. Trade Representative. Trump nominated Robert Lighthizer for the post, but there has yet to be a committee hearing scheduled.
Trump previously said trade policy would be led by Commerce Secretary Wilbur Ross and Peter Navarro, who helms a newly created trade council, but only the office of the USTR "has the resources to actually do the negotiation," according to Jeff Schott, senior fellow at the Peterson Institute for International Economics.
Formal negotiations with Canada and Mexico can't happen until after the U.S. finishes its deliberations with Congress, despite Mexico on February 1 opening its own 90-day window to consult with its Senate and businesses. That process, Schott says, "is to conduct contingency plans depending on what the U.S. does."
Secretary of State Rex Tillerson and Secretary of Homeland Security John Kelly will visit Mexico City on February 22 and 23, according to the State Department's twitter feed.
Trump could pull the U.S. out of NAFTA without Congressional approval, according to Oxford Economics, as he did by executive order his first week in office for the U.S. involvement in the Trans-Pacific Partnership. But that could be subject to legal challenge.
At a Florida rally on Feb. 18, Trump called that 12-nation deal with nations in Asia and Latin America a "job-killing disaster" and pointed to his commitment to undo trade deals.
Withdrawing from TPP, however, was much simpler: It had not yet been passed by Congress.
NAFTA, on the other hand, has been in practice for more than two decades, which means a hasty exit could cause chaos for businesses.
