Meanwhile, it is not the only poll suggesting negative attitudes to the economy are brewing. According to an April CNBC poll of 1,000 Americans, 43 percent approve of Trump's handling of the economy and 55 percent disapprove, the first time a CNBC survey has shown the president with a net negative on the economy.

In its quarterly outlook on the world economy, the International Monetary Fund projected slower economic growth for the world, including the U.S., in the wake of President Trump’s tariffs.
