The rule governing comment on the jobs data was put in place for at least two reasons. First, financial markets respond immediately to the monthly report, and a premature release could lead to insider trading or market manipulation.
Second, there has been a strong effort to insulate this information from political leaders, as advance discussion of the data could make it seem politicized. During the Obama administration, Trump routinely said that the numbers in the jobs report had been tampered with to bolster Democrats’ political prospects.
