An unexpectedly weak jobs report for July brings into question the health of the U.S. economy as President Donald Trump pushes ahead with his tariff policy.

President Donald Trump on Friday had his team remove the head of the agency that produces the monthly jobs figures, after a weak report showed hiring slowed and was much weaker in April and May than previously reported.

Trump's public frustrations with the economics and statistics agency appear to date back to his 2016 presidential campaign. "Don't believe those phony numbers," then-candidate Trump said in his New Hampshire victory speech during his first campaign for the White House.
