There were a couple of mass emails sent. One before the crash and another after the crash. From another source:
The email, sent from President Trump’s Office of Personnel Management to employees across the sprawling federal government, arrived just before 8:30 p.m. Thursday — almost exactly 24 hours after an air crash in Washington that killed 67 people. The message reiterated an offer earlier this week from the administration encouraging federal employees to seek new jobs in the private sector — and did so in terms that appeared to denigrate their contributions, if not cast them as lazy.
