Obama officials leaked classified document's serial codes.
In other words, this confirms that an effort has been made from day one to ensure that information that can embarrass Trump can be readily used; it's the same tactic used when Nixon detractors insinuated he was in Dallas on the day of the JFK assassination.
The report contradicts itself:
So, are they just showing the committee the documents? Or are the documents now out of their proper place and are in the safe at the Intelligence Committee? Which is it?
They gave the Committee an unclassified list of document serial numbers to prove that these documents existed. So if the Intel Committee asked to see the documents themselves and the Trump Administration said they didn't exist or weren't there, then it would be clear evidence of something dodgy.
