The US Labor Department's internal watchdog has launched an investigation into how it gathers jobs and inflation data after intense White House criticism of the agency.
The office of the Labor Department's inspector general said it had launched a probe to look at the "challenges" the Bureau of Labor Statistics (BLS) faces gathering and updating the information.
The move comes a day after the agency issued a revision to job figures showing growth last year was far weaker than it had previously estimated.
Last month, President Donald Trump fired the head of the BLS, saying without evidence that she had rigged the job numbers to make him look bad.
In a letter to acting commissioner William Wiatrowski, the Labor Department's office of inspector general said the decision to launch the probe was a response to the job report revisions and BLS moves to reduce collection of price information.
