When President Donald Trump blamed diversity, equity, and inclusion programs for the deadly January crash at Ronald Reagan Washington National Airport, some aviation officials were appalled. Some were simply perplexed. But few officials inside the Federal Aviation Administration took the president’s remarks seriously.

Not so for the political leadership of the Department of Transportation. The FAA’s parent agency agreed in March to spend as much as $2.1 million on an investigation into DEI policies and their impact on recent safety incidents. To conduct that investigation, the Trump administration has turned to Alex Spiro, a former prosecutor and a prominent defense attorney who has represented Elon Musk, among other billionaires and celebrities.

I obtained the “scope of work” document for Spiro’s investigation, which is marked “privileged” and “confidential” and has not been previously reported. It shows how the president’s musings—his accusations, he said at the time, were based on “very strong opinions and ideas”—translate into taxpayer-funded government action. It also reveals the cost of the administration’s fixation on DEI at a time when the FAA is struggling to hire and retain air-traffic controllers, linchpins of aviation safety, and when Sean Duffy, the transportation secretary, is seeking funds to overhaul the country’s antiquated air-traffic-control system. Recent radar outages at Newark Liberty International Airport have caused severe flight delays and spotlighted just how deep technology and staffing problems run.

The investigation by Spiro, a partner at the elite firm Quinn Emanuel Urquhart & Sullivan, is due to conclude soon, a person familiar with the dynamics told me, speaking on the condition of anonymity because of the confidentiality of the work. Contrary to what Trump may hope, it’s not expected to find that programs aimed at ensuring representation for women and people of color are responsible for this year’s string of aviation disasters, including the January crash at Reagan airport, which killed 67 people and prompted Trump’s tirade against DEI.
