WASHINGTON — Gary Cohn, the White House’s top economic adviser, announced Tuesday that he was leaving the administration amid a major internal clash over President Trump’s sharp and sudden pivot toward protectionist trade policies.
Cohn, the former president of Goldman Sachs who had been an interlocutor between the Trump administration and the business community, still plans to stay in his job for several weeks, a person briefed on his plans said.
He plans to continue to push back on Trump’s planned tariffs on steel and aluminum imports, which have threatened to touch off a global trade war, said the person who spoke on condition of anonymity to discuss Cohn’s plans.
But his departure as National Economic Council director leaves the White House without a financial heavyweight who business executives and foreign leaders believed had served as a counter to Trump’s protectionist impulses and as a moderating force in other areas.
Cohn’s resignation announcement is the latest jolt to a White House that has been especially tumultuous in recent weeks and unable to retain its top talent. Last week, communications director Hope Hicks and deputy communications director Josh Raffel announced their resignations.
In February, staff secretary Rob Porter was forced out over domestic abuse allegations. And the year began with the departures of deputy national security adviser Dina Powell as well as Cohn’s deputy on the National Economic Council, Jeremy Katz.
Taken together, the departures largely diminish the faction of free trade advocates who not only held center-right views on trade and other issues, but were seen as moderating forces inside a West Wing otherwise populated by more hardline conservatives.
Bloomberg reported that Trump demanded Cohn’s cooperation on tariffs in a meeting in the Oval Office Tuesday — asking Cohn directly if he would support his decision to move forward with the plan.
Cohn would not offer his support, according to two people familiar with the episode — and just hours later, the White House announced Cohn’s resignation.
In a way, Cohn’s resignationwas exactly as Trump had predicted this week, telling associates that he expected Cohn to quit if he went ahead with the tariffs. Trump is expected to announce the moves — a 25 percent tariff on steel and 10 percent on aluminum — as early as this week.
The New York Times reported that Cohn’s resignation followed conversations he held with the president in recent weeks about the possibility of replacing John F. Kelly as White House chief of staff, said people who were briefed on the matter. The president never formally offered Cohn the job, those people insisted, but Trump had discussions with him about whether he would be interested.
Trump, during the trade policy meeting in the Oval Office Tuesday, asked for an update on the legal paperwork that will make the tariffs official and discussed the timing of the signing of the tariffs order. He then sought confirmation that everyone — and especially Cohn — was willing to stand behind him.
‘‘It has been an honor to serve my country and enact pro-growth economic policies to benefit the American people, in particular the passage of historic tax reform,’’ Cohn said in a statement. ‘‘I am grateful to the President for giving me this opportunity and wish him and the Administration great success in the future.’’
Trump said in a statement, ‘‘Gary has been my chief economic advisor and did a superb job in driving our agenda, helping to deliver historic tax cuts and reforms and unleashing the American economy once again. He is a rare talent, and I thank him for his dedicated service to the American people.’’
In the past week, Trump has said he will impose tariffs that hit imports from Canada, Germany, Mexico, the United Kingdom, Turkey, South Korea, and a range of other countries, threatening to escalate the penalties if any nation dares to retaliate.
This came after Cohn spent months trying to steer Trump away from tariffs and trade wars, with Cohn eventually being outmaneuvered by Commerce Secretary Wilbur Ross, trade adviser Peter Navarro, and ultimately Trump himself.
Trump could cast a wide net in searching for a replacement, though he has told advisers that he wants to consider Larry Kudlow, a media personality and 2016 campaign adviser, according to several people briefed on Trump’s discussions.
In many ways, Cohn’s NEC was one of the most stable parts of the White House, avoiding the scandals and revolving-door image that the National Security Council and other offices endured. But Cohn and the president had an on-again, off-again relationship, with relations becoming chilly after Cohn criticized Trump’s response to a white supremacist rally in Charlottesville, Va.
Cohn’s departure rattled a number of business executives around the country, many of whom saw the Wall Street veteran as a free market capitalist who would speak out against those who wanted to pick fights with global trading partners.
‘‘The protectionists are clearly running the show right now, the economic nationalists are,’’ said Brian Gardner, managing director of Keefe, Bruyette & Woods. ‘‘If they replaced [Cohn] with another economic nationalist, then it really gets dicey for the markets and investors.’’
Kudlow has been largely supportive of Trump’s economic agenda, but he has expressed concerns about Trump’s moves on trade. He had in recent days encouraged Cohn to stay. Reached by phone on Tuesday, Kudlow declined to comment.
Cohn’s departure was first reported by the New York Times and immediately confirmed by White House officials.
Cohn had first discussed with Trump the possibility of departing the White House in January, a person familiar with the conversation said, always having had the goal of staying in the Trump administration for around a year. An infrastructure plan Cohn had spent months trying to design was supposed to be the focus of the early part of this year but it was repeatedly sidelined.
It was Cohn and Treasury Secretary Steven Mnuchin who helped convince Trump to postpone ripping up trade agreements or imposing tariffs late last year to avoid enraging congressional Republicans during the tax debate.
Cohn was not expected to stay long into 2018, but he did outlast the first wave of departures in January and February. The stock market soared in 2017 in part because of global growth but also because of investor enthusiasm over Trump’s deregulatory agenda and tax cut focus, items that Cohn helped design.
But people close to Cohn said he found the pivot toward protectionism this year infuriating, and said he wouldn’t force himself to go out in public and defend it.
