Mar-a-Lago property manager Carlos De Oliveira pleaded not guilty Tuesday to conspiring with Donald Trump to attempt to remove security footage sought by investigators investigating the former president’s hoarding of classified documents.

A lawyer for De Oliveira entered the plea on his behalf during a brief hearing in federal court in Fort Pierce, Florida, where Trump is accused of illegally holding top secret data at his Palm Beach club and thwarting government efforts to get them back.

It is the third trial for De Oliveira, who had twice previously postponed his arraignment because he had not yet found a lawyer in Florida, which is required by the court’s rules.

De Oliveira only spoke to answer the magistrate’s questions, such as whether he understood the charges against him. De Oliveira and his new attorney, Donnie Murrell of West Palm Beach, walked out of the courthouse without speaking to reporters.

De Oliveira’s settlement comes a day after Trump was indicted in a fourth criminal case. On Monday night, Trump and 18 allies were named in a case from Fulton County, Georgia, alleging attempts by him and his supporters to illegally interfere in that state’s 2020 election.

In the Mar-a-Lago case, Trump and his clerk, Walt Nauta, were initially charged in June in one of two cases brought by Special Counsel Jack Smith. Smith has also accused Republican Trump in Washington of illegal conspiracy to reverse his 2020 election loss to Democrat Joe Biden.

An updated indictment unsealed late last month led to more charges against Trump and Nauta, adding De Oliveira to the Florida case. Trump faces dozens of felonies in the classified documents case, and Smith’s new charges included additional counts of obstruction and willful withholding of national defense information.

Trump and Nauta have also pleaded not guilty. The former president denies any allegations.

De Oliveira, Trump and Nauta are charged with, among other charges, conspiracy to obstruct justice in the case arising from classified government documents found at Mar-a-Lago following the end of Trump’s presidency in 2021. De Oliveira is also charged with lying to researchers. Prosecutors allege he falsely claimed he didn’t even see boxes move into Mar-a-Lago after Trump left the White House.

The trial begins in May before U.S. District Judge Aileen Cannon. If the date holds, it would come close to a separate trial in New York against Trump on dozens of state charges for falsifying business records related to an alleged hush money payment to a porn actor.

The allegations in the latest indictment focus on security footage. Prosecutors say Trump attempted to remove it after investigators sent a subpoena to do so in June 2022. Prosecutors have not claimed that the footage was actually removed.

Prosecutors say De Oliveira asked an IT worker how long the server kept footage and told the employee the boss wanted it removed. When the employee said he didn’t believe he was capable of doing this, De Oliveira insisted that the boss wanted it and asked, What are we going to do?

The Mar-a-Lago video could ultimately become vital to the government case because, prosecutors said, it shows Nauta moving boxes in and out of a storage unit, an act allegedly committed at Trump’s direction and in an attempt to hide documents belonging not only to detectives but also to Trump’s own lawyers.
