Trump tweeted a big hint about the monthly employment numbers, one of the most closely watched pieces of government data.
In March of a year ago, then-White House press secretary Sean Spicer ran afoul of the directive when he took to Twitter 22 minutes after the Bureau of Labor Statistics had released the jobs report for the previous month to tout that the 235,000 net jobs gain and the slight decline in the unemployment rate were "great news for American workers".
Trump sent out his tweet at 7:21 AM on Friday; the jobs report was released at 8:30 AM.
"This could go on for a whole bunch more years, in my judgement", White House economic advisor Larry Kudlow told CNBC.
Though Trump's tweet suggested a strong jobs report, it may not have been the White House's first time giving clues on the numbers.
If one can draw a postive inference from the fact that the President tweeted a "heads-up" an hour in advance of the jobs report, what conclusion will traders reach if he fails to do so in the future, and what impact will that have on markets?
In the span of time between when Trump posted his tweet and when the jobs report was released, USA treasury yields shot up. Trump has made the roaring stock market a centerpiece of his administration and re-election campaign, though Wall Street has faced recent uncertainty due to the administration's saber-rattling over tariffs.
Trump supporters say the president's economic plan and hard-bargaining with other countries is paying dividends for US workers.
Trump is not the first USA president to chart the White House's own schedule for commenting on major economic reports. He tweeted "If during the Clinton or Obama Administrations there had been a statement from POTUS or anyone senior official in the morning before the Employment Report it would have been a major scandal-with all sorts of investigations following on".
He said that Canada, for example, "just kicks us on lumber and puts people out of work in Maine".
The President teased the Jobs Report an hour before it was officially released.
So, 69 minutes before anybody was supposed to know what was in this morning's jobs report, Trump signaled that it would be good.
"I don't think he gave anything away, incidentally", Kudlow added.
"1985 federal directive on #JobsReport states: "employees of the Executive Branch shall not comment publicly on the data until at least one hour after the official release time".
The former chairman of the council of economic advisers said that Trump broke the law.
President Donald Trump talks to reporters as he boards Air Force One to depart for a trip to Houston and Dallas, Texas, from Joint Base Andrews in Maryland, May 31, 2018.
He added that he did not want to say more that would get ahead of the curve.
But former Obama White House press secretary Jay Carney took it a step further, saying that the same would be true under both Bush administrations:Ari Fleischer, former White House press secretary to President George W. Bush, seemed to concur.
"You can read into that 10 different things", Kudlow said.
