The Wall Street Journal was first to report Thursday that Special Counsel Robert Mueller issued a subpoena mid-October to more than a dozen top Trump campaign officials. It is his "first official order for information from the campaign."
Mueller reportedly is seeking documents related to various search terms.
CNBC:
None of those who received the subpoena were compelled to testify before a grand jury, the Journal reported.
"Sending a subpoena to an entity that says it has been cooperating with document requests isn't unusual in cases in which prosecutors have some concern that their demands aren't being met promptly or aren't being entirely fulfilled," the Journal wrote, citing former prosecutors.
CNN's sources offer conflicting assessments of what Mueller's move means:
One source described it as a "cleanup" subpoena, expanding the search terms.
(...)
The second source calls the subpoena "bookkeeping" at the end of a grand jury process. That source called the subpoena "largely perfunctory" and said much of it will be "duplicative" of documents the special counsel already has.
One source says fulfilling the new request could take months because of the amount being asked for, while the other says it likely won't delay things beyond January.
