The U.S. jobless rate fell to an 18-year low of 3.8 percent in May, according to new figures released Friday by the Bureau of Labor Statistics. Employers filled 223,000 jobs, with average hourly wages up 2.7 percent from a year earlier. However, the strong performance was overshadowed by an early-morning tweet by President Trump, who posted that he was “looking forward” to the report some 69 minutes before their release—breaching a 1985 rule that prohibits any federal workers from commenting on it until an hour afterward or at any time before. The Washington Post reports Treasury bond yields moved sharply in the moments after Trump’s tweet. The chief of the Council of Economic Advisers traditionally receives the report the day before the public, and presidents get to see it after that. Until today, no president had ever tipped the public about what the report shows before the closely guarded numbers are released, according to the Post.
