The federal judge overseeing the case against Paul Manafort in Washington said Tuesday that special counsel Robert Mueller must reveal the identities of the unnamed people he’s hoping to use in the case against the former Trump campaign chairman.

Judge Amy Berman Jackson said Mueller must turn over the names of any individuals or entities alleged to be the “others, including former senior foreign politicians” whom Manafort “caused and aided and abetted” to act as unregistered foreign agents on his behalf. Jackson said those names, which Manafort’s side has been demanding, must be given to Manafort’s defense team by Friday.
