Signing the memorandum in the Oval Office, Trump repeated – without evidence – his earlier assertions that federal diversity programs contributed to a helicopter and a regional jet colliding near Washington.
"Incompetence might have played a role, we'll let you know that," Trump said to reporters.
He said the memorandum can help ensure that "we have very strong people running" key aviation agencies.
