Yuscil Taveras' July grand jury testimony resulted in a superseding indictment against the former president and others in the classified documents case.
Federal prosecutors said the witness, reportedly an IT director at Mar-a-Lago, has retracted “prior false testimony” after switching attorneys.
The now-indicted lawyer reportedly made the sojourn to Trump's home with a desperate plea.
Carlos De Oliveira is accused of scheming with the ex-president to try deleting security footage sought by investigators probing the hoarding of classified documents.
Walt Nauta and Carlos De Oliveira appeared in federal court in Florida to face charges in the case accusing Trump of illegally hoarding classified documents.
His lawyers asked the judge to reestablish the "SCIF" that existed at Mar-a-Lago during Trump’s presidency to review the documents he is accused of illegally retaining.
The conservative attorney had a stark warning for Mar-a-Lago employee Carlos De Oliveira.
Federal prosecutors added to their case on Thursday, alleging that Trump and associates tried to delete Mar-a-Lago surveillance footage.
Carlos De Oliveira was the Mar-a-Lago property manager who allegedly helped move boxes of classified documents.
It will be U.S. District Judge Aileen Cannon’s first time hearing arguments in the case since the former president's indictment last month.
