On July 25, 2019 presiding Federal Judge Emmet T. Sullivan, ordered the well-known law firm of Covington and Burling LLP to 'promptly turn over the entire file' on Flynn to his new defense attorney Sidney Powell. The order was made under threat of a hearing before the District of Columbia Ethics Counsel. The law firm turned over what is described as a 'voluminous' amount of documents but it apparently wasn't all the documents.

On Wednesday, the law firm turned over more documents and suggested in a supplemental notice filed with the court that there may be even be more documents not yet produced.

"In reviewing materials in response to the Court's March 6, 2020 Order (Doc. 174) to respond to Mr. Flynn's specific allegations in his Supplemental Motion to Withdraw Plea of Guilty, however, we have found emails and two pages of handwritten notes that were not previously transferred to successor counsel," the notice submitted by Flynn's former lawyers Robert Kelner and Stephan P. Anthony stated.
