I would imagine that anytime a report is going to be released and it's going to be filled with stuff like this:

The Ukraine call complaint against Trump is riddled not with evidence directly witnessed by the complainant, but with repeated references to what anonymous officials allegedly told the complainant: “I have received information from multiple U.S. Government officials,” “officials have informed me,” “officials with direct knowledge of the call informed me,” “the White House officials who told me this information,” “I was told by White House officials,” “the officials I spoke with,” “I was told that a State Department official,” “I learned from multiple U.S. officials,” “One White House official described this act,” “Based on multiple readouts of these meetings recounted to me,” “I also learned from multiple U.S. officials,” “The U.S. officials characterized this meeting,” “multiple U.S. officials told me,” “I learned from U.S. officials,” “I also learned from a U.S. official,” “several U.S. officials told me,” “I heard from multiple U.S. officials,” and “multiple U.S. officials told me.”

It would be pertinent to send out a clarification of what's true and not true. Doesn't surprise me it inadvertently gets sent out to dems regardless of who sent it out...the way I look at it is if sent out "supposedly" by accident it's just more leaking to undermine the president's credibility, if sent out deliberately there's no better way to highlight the truth to everyone then to hand the dems something they will dissipate to every news organization in the world...in other words they become the messenger of the truth to an audience they normally wouldn't reach. (You have to start thinking about how the other side thinks.) (if true it's masterful) (lol)

You know this is beginning to look more and more like a set up, they even changed up the whistle blower form to omit the requirement that a whistle blower must have first hand knowledge to file a report....that requirement was changed in August....how convenient. Give it time, the dems will finish hanging their own selves.
