Gary Cohn, President Trump’s top economic adviser, is resigning. The administration offered few details but said that Cohn is expected to leave in the coming weeks.

"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,” Trump said in a statement. “He is a rare talent, and I thank him for his dedicated service to the American people."

So what went wrong? This time it appears to be tariffs. Cohn reportedly disagreed strongly with President Trump's announcement last week that he will impose a 25 percent tariff on steel imports and a 10 percent tariff on aluminum imports.

Gary Rivlin, an investigative fellow at the Investigative Fund, who most recently tracked Gary Cohn’s role in the White House for The Intercept, and Alex Lawson, senior reporter on international trade at Law360, discuss the significance of Cohn's departure.
