"Looking forward to seeing the employment numbers at 8:30 [12:30 p.m. GMT] this morning," Trump said in a Twitter message at 7:21 a.m. local time.
A little over an hour later, the Bureau of Labor Statistics reported that 223,000 jobs were created in May, and the unemployment rate fell to 3.8 percent, its lowest level since 1969.
US presidents have long refrained from commenting on the jobs report before its official release. The Chairman of the Council of Economic Advisers receives the report the day before its publication and is allowed to share it with the president, but neither are supposed to comment on it until its official release.
US Treasury yields rose sharply within seconds of Trump's post, the Washington Post reported, adding that it appeared to be the first time that the president commented on the data ahead of the report's release.
