Special Counsel Robert Mueller is seeking a May 14 trial date for former Trump campaign chairman Paul Manafort and his business associate, Rick Gates.

Prosecutors working for Mueller’s team filed the request in federal court in Washington, D.C. on Friday.

Manafort and Gates were indicted on Oct. 30 on 12 counts, including conspiracy against the U.S., conspiracy to launder money and making false statements.

None of the charges appear to be related to Manafort’s work on the Trump campaign. Instead, they largely stem from Manafort’s work for a Ukrainian political party that is aligned with the Russian government.

Friday’s court filing provides new details of the documents that will be used as part of the discovery process in the case.

Prosecutors say they have more than 590,000 items, including financial records, email communications, corporate records. They also have around 2,200 so-called “hot” documents, a term used to signify significant pieces of evidence.

Manafort, who left the Trump campaign in Aug. 2016, has protested Mueller’s actions in the case. Earlier this month he sued Mueller, the Justice Department and Deputy Attorney General Rod Rosenstein, alleging that the special counsel’s office has gone beyond its initial mandate in the Russia investigation.

Manafort argued that he faces charges for activities he undertook years before joining the Trump campaign.
