Christine Lagarde, former head of the International Monetary Fund, says President Donald Trump is responsible for many of the risks facing the global economy, and warns that the rise of nationalism is not the answer to economic fears.

In an interview aired Sunday night on CBS’s “60 Minutes,” Lagarde — who was confirmed last week as the next president of the European Central Bank — said Trump’s unpredictability has forced investors to stop taking risks and that the U.S.-China trade war is “going to give a big haircut to the global economy.”
