Following a recent new order from a federal appeals court, Donald Trump Mar-a-Lago case defense attorney, Evan Corcoran, is expected to testify before the grand jury probing classified materials seized at Mar-a-Lago on Friday, according to a source familiar with the situation who spoke to CNN.

To help the criminal investigation into the suspected mishandling of confidential data, the US DC Circuit Court of Appeals ruled that Corcoran must deliver more testimony and hand over documents about the former president.

According to the source, the Trump administration will likely wait to file an appeal with the Supreme Court.

"There is no factual or legal basis or substance to any case against President Trump," and "prosecutors only attack lawyers when they have no case whatsoever," an official Trump spokeswoman stated in response to the ruling.

Less than a day after Trump tried to delay Corcoran's testimony, a panel of three justices in the appellate court announced that they would not hear Trump's request to do so. This is significant since the special counsel investigation is trying to obtain material that might determine the outcome of a federal criminal case against Trump.

The Justice Department has successfully claimed in court that prosecutors have enough proof that Trump's discussions with the attorney were a component of a potential felony that they could breach the confidentiality of the two men's communications.

Evan Corcoran Ordered To Submit Notes in Donald Trump Mar-a-Lago Case

It has been reported that the case hinges on Corcoran's handwritten notes and audio transcripts of his representation of the former president in the Donald Trump Mar-a-Lago case, The Guardian noted.

Attorney-client privilege and the work-product doctrine were breached in a court decision last week, but the US appeals court for the DC Circuit rejected two requests from Trump and his lawyer on Wednesday to halt the order.

For Trump's part, losing the appeal means that Corcoran must testify before the grand jury investigating his probable obstruction of justice and improper possession of national security materials at Mar-a-Lago.

Donald Trump Mar-a-Lago Case

After taking hundreds of federal documents, including many classified, Trump kept them at his Mar-a-Lago club in Palm Beach, prompting a probe by the Justice Department at least as far back as last year.

When a president leaves office, they must legally hand over this paperwork.

Jack Smith, appointed to oversee the Donald Trump classified documents scandal, is investigating whether Trump and others obstructed justice by hindering federal agents' attempts to retrieve the records in the months preceding the August 2018 FBI raid on Mar-a-Lago.

Corcoran told another Trump lawyer, Christina Bobb, to give DOJ officials a written statement saying that a thorough search for classified records in Trump's possession had not turned up any more documents. However, the raid found that this claim was false, said CNBC.

Trump appealed Judge Beryl Howell's ruling to the United States Court of Appeals for the District of Columbia.

The Donald Trump Mar-a-Lago case is included on the public docket of the appeals court, which implies that the court accepted the appeal on Tuesday and stayed Howell's order later that day, even if the case itself is sealed.

The court then gave the DOJ until 6 a.m. on Wednesday to reply to the appeal requests. Trump's legal team was given until midnight to complete the necessary paperwork.
