Inside Russia's divisive Facebook pages

One of the key Russian Facebook pages was colored with hot-button words and phrases like "illegal alien," ''Sharia law" and "welfare state," AP's Ryan Nakashima and Larry Fenn find:

• "'Being Patriotic' was among 470 pages and accounts that Facebook shut down ... in response to a congressional probe into Russian meddling in last year's election."
• "While Facebook says it deleted the posts this week, the AP was able to perform a content analysis based on the 500 most popular posts on the page, which was one of six Russia-influenced Facebook pages examined by Jonathan Albright, research director at the Tow Center for Digital Journalism at Columbia University."
