Mexico deal gives only temporary relief

President Trump’s last-minute immigration deal that staved off threatened tariffs on Mexican imports let businesses breathe a short sigh of relief.

But only a short one, because the president left on the table the possibility he might still hit the country with duties if he sees fit. It’s a prospect that business executives and economists say might further undercut an American economy in which growth has already been hampered by a trade war intensifying since last year.
