The packet, according to sources and photocopies shown by Raskin, arrived at the State Department in an envelope indicating it was from the White House. Within the envelope, the paperwork was contained in multiple folders from Trump hotels.

Democrats quickly blasted the packet as "disinformation" and "propaganda" that contained "conspiracy theories."

Both Raskin and a Democratic source familiar with the briefing pointed to Giuliani as the likely origin of the packet.

"This was just another attempt by the White House to peddle Rudy Giuliani conspiracy theories," the source said earlier Wednesday.

"If it really did not come directly from the White House, I would guess that it was Giuliani. ... Giuliani's name is all over it," Raskin said. "Somebody should ask Giuliani if he knows anything about this."
