Facebook has been looking into posts supporting Sen. Bernie Sanders' 2020 presidential election campaign that were deemed suspicious, The Wall Street Journal reported Monday, citing unnamed sources. Facebook confirmed it's investigating just one claim by a researcher, but said it wasn't able to validate the researcher's claims. It also hasn't been notified by the intelligence community, a spokesperson said.
"We investigate each credible claim we receive, just as we did in this instance when an outside researcher contacted us," a Facebook spokesperson said in an emailed statement. "Had we found a campaign of coordinated inauthentic behavior, we would've removed it and announced it publicly, just as we did more than 50 times last year."
