Former New Jersey Gov. Chris Christie ripped President Donald Trump as a “petulant child” on Sunday for his dramatic firing of the head of the Bureau of Labor Statistics. Christie said Trump just needed “someone to blame because he won’t take the responsibility himself” about the July jobs report,

President Donald Trump on Friday had his team remove the head of the agency that produces the monthly jobs figures, after a weak report showed hiring slowed and was much weaker in April and May than previously reported.

Federal government employment fell again in July, with a loss of 12,000 jobs, according to the report. The sector has lost 84,000 jobs since the start of the year. The report notes that employees who are on paid leave or are receiving ongoing severance pay are considered employed, and so are not included in this tally.
