On Friday, President Trump fired the head of the Bureau of Labor Statistics, Erika McEntarfer, after the July jobs report showed job growth had stagnated.

President Donald Trump claimed without evidence that the massive revisions to the latest jobs report constituted a “scam.” Yet revisions by the BLS were neither historic nor evidence of corruption.

President Trump’s pick to run the federal agency that produces the critical U.S. jobs report might not be able to make it more reliable — and a new commissioner could even make the problems worse.
