What’s not known is who is paying for the continuing research? Fusion GPS officials could not be reached immediately for comment.

Marc E. Elias, who was a lawyer representing the Clinton campaign and the DNC allegedly retained Fusion GPS, but the campaign failed to disclose those payments on its finance records.

On Saturday, New York Post‘s Paul Sperry suggested he may know who Fusion GPS’s new client is — None other than special counsel Robert Mueller.

“Fusion GPS co-founder Simpson is STILL actively investigating Trump for Russian ties but REFUSES to name his new client (Special Counsel MUELLER’s office?) and Democrats are trying to block Republicans from confirming the identify of his new client (b/c it’s MUELLER?),” tweeted Sperry.

On Thursday, the House Permanent Select Committee on Intelligence released the transcript from its interview with Fusion GPS co-founder Glenn Simpson from last November.
