1) Of the group of 3,000 ads turned over to Congress by Facebook, a majority of the impressions came after the election, not before. Indeed, in a news release Monday, Facebook said 56 percent of the ads’ impressions came after the 2016 vote.

2) Twenty-five percent of the ads were never seen by anybody. (Facebook also revealed that Monday.)

3) Most of the ads, which Facebook estimates were seen by a total of 10 million people in the United States, never mentioned the election or any candidate. “The vast majority of ads run by these accounts didn’t specifically reference the U.S. presidential election, voting or a particular candidate,” Facebook said in a Sept. 6 news release.
