Seems like the broadest-based burst of interest actually came in mid-December—two weeks before the Kislyak sanctions call. Who was Flynn talking to then? Also, can we see what this data set looks like before Election Day, @RichardGrenell?
Here’s the full document, revealing that Grenell personally requested this stuff from the NSA by email all of ten days ago. grassley.senate.gov/sites/default/… 
By my count, 30 US officials asked for US person info in a foreign intel report btw Dec 14-16. These were officials all over the globe--at the UN, at NATO, at FBI, at CIA, at Treasury, at the Energy Dept, officials who focused on Syria and Russia, the ambassador in Moscow, etc.
The 30 officials couldn't have known until later that they were asking about Flynn; his name was masked in the initial report.
These requests occur about two weeks before the Kislyak-Flynn sanctions call, and two weeks after Kushner and Flynn met Kislyak at Trump Tower.

The Mueller Report, fwiw, doesn't identify anything relating to Flynn going on that week. The only nearby items in their timeline are Kushner meeting w/ Sergey Gorkov (the head of a sanctioned Russian state bank) on Dec. 13 and his assistant meeting w/ Kislyak the day before.
For more evidence that this confected brouhaha has nothing to do with the Flynn-Kislyak sanctions calls, read Comey's testimony. They never put the calls into any finished intel reports. And for those briefed, FBI made the call to unmask Flynn's name. courtlistener.com/recap/gov.usco…
The only wrongdoing we really know of is someone leaked Flynn’s sanctions calls—highly classified information—to a WaPo columnist. Comey’s testimony indicates that info flowed from FBI to Clapper to the WH.
Comey says the FBI’s people decided to unmask Flynn in briefing the sanctions calls. He says the sanctions calls weren’t the subject of widely disseminated intel reports that could’ve led to all these document unmasking requests, most of which are earlier in time anyway.
So Grenell’s document is a weird distraction, a purposeless frolic. Unless the facts are wildly at odds with Comey’s testimony, it can’t answer who leaked the sanctions calls to Ignatius. And we don’t, so far, know of any other wrongdoing for it to speak to.
The Trump DOJ’s problem with the Flynn prosecution is what they call the lack of a proper predicate for interviewing Flynn. (Nevermind his lie to the VP.) But there’s really no known predicate for looking into these Obama officials whose business Grenell tipped into the street.
