President Donald Trump complained to his aides about the lack of progress being made on trade deals as he was debating whether to push back his tariff deadlines yet again, according to a report.The president announced on Monday he was imposing a new wave of 25- to 40-percent tariffs on products from more than a dozen countries—including key trading partners such as Japan and South Korea—unless those countries reach new trade deals with the U.

The pause on the biggest of Trump's tariffs won't pass this week, as planned, but the problems they present still loom large.
