National Economic Council Director Kevin Hassett launched a broadside against the Federal Reserve Bank of New York for publishing research that found the Trump administration’s tariff policies hurt U.S. companies.

Hassett said the authors of the research should be punished, a new escalation in the Trump administration’s conflict with the Federal Reserve system. The administration has faced pushback for pressuring the central bank to lower interest rates.
