The Ads That Russia Bought On Facebook
A number of advertisements took aim at Hillary Clinton, Donald Trump's main rival in the 2016 presidential election.
The issue of Islam and the supposed threat Muslims posed to U.S. society also featured in several ads.
Some ads seemed to tap into the highly charged issue of race relations at a time when the Black Lives Matter movement was sweeping across America.
This ad seemed aimed at stoking up antipathy toward the Black Lives Matter campaign against police violence.
The second amendment to the U.S. Constitution and the right to bear arms were another hot-button issue that this ad seemed to be touching on.
There were also ads on the subject of border security and immigrants, which was a major talking point in the 2016 election campaign.
