Former White House chief economic advisor Gary Cohn lashed out at some of his former colleagues, charging in a radio interview that the U.S. is losing the trade war as administration officials pursue a strategy that hasn't worked. Cohn, President Donald Trump's first director of the National Economic Council, specifically pointed his finger at Peter Navarro, who serves as director of the National Trade Council, and Commerce Secretary Wilbur Ross for drawing the country into a misdirected tariff battle.

"Tariffs don't work. If anything, they hurt the economy because if you're a typical American worker, you have a finite amount of income to spend," the former Goldman Sachs executive told "Freakonomics" radio in an interview broadcast Wednesday. "If you have to spend more on the necessity products that you need to live, you have less to spend on the services that you want to buy." When interviewer Stephen J. Dubner suggested that all other economists except for one — Navarro — would agree on that point, Cohn said, "There's only one in the world. That we know of."

Among the other revelations from his time in the White House, Cohn said a tipping point for him leaving was a meeting Navarro and Ross secretly set up with heads of the steel and aluminum industry to notify them that the administration was planning to levy tariffs on imports of the metals. "What happened in the White House is we got to a point, unfortunately, where one or two people decided that they were going to no longer be part of a process and a debate," he said. Asked to confirm that it was Navarro and Ross who set up the meeting, Cohn said, "Yes. Those are the two people. When the process breaks down, then you're, sort of, in my mind, living in chaos. I don't want to live in a chaotic organization."

'The president needs a win'

Cohn served in the post from the beginning of the Trump administration in January 2017 until April 2, 2018. Chief among his achievements was the passage of the biggest tax cut in U.S. history that slashed the corporate rate from 36 percent to 21 percent and redrew the individual income tax brackets to give lower earners double the standard deduction. However, he also had several high-profile disagreements with the administration, including one point where he nearly resigned following Trump's comments on a deadly white supremacist rally in Charlottesville, Virginia.
