In its hurry to use its final days in power to execute federal prisoners, the administration of President Donald Trump has trampled over an array of barriers, both legal and practical, according to court records that have not been previously reported.

Officials gave public explanations for their choice of which prisoners should die that misstated key facts from the cases. They moved ahead with executions in the middle of the night. They left one prisoner strapped to the gurney while lawyers worked to remove a court order. They executed a second prisoner while an appeal was still pending, leaving the court to then dismiss the appeal as “moot" because the man was already dead. They bought drugs from a secret pharmacy that failed a quality test. They hired private executioners and paid them in cash.
