The federal agency responsible for traffic safety, which has been investigating whether self-driving technology in Tesla vehicles played a role in the death of a pedestrian, laid off 4% of its employees Feb. 14, a Transportation Department spokesperson said Saturday.

The traffic safety agency did not say whether any of its fired employees were involved in investigations of Tesla, whose CEO, Elon Musk, is leading a team at the Department of Government Efficiency established by President Donald Trump.

Musk’s team has been forcing layoffs at numerous government agencies as part of an effort to reshape the federal bureaucracy.

Musk has retained control of Tesla while spending much of his time in Washington.

The National Highway Traffic Safety Administration has three active investigations of Tesla, according to agency documents.

Even after the layoffs, the agency continues to employ more people than at the beginning of the Biden administration, the agency said in a statement.
