In a tweet, Stamos said his role has changed inside of Facebook but that he remains "fully engaged".
Alex Stamos announced the change in his work role after The New York Times reported he was leaving Facebook in the wake of internal clashes over how to deal with Russian actors using the platform to spread false or exaggerated stories to cause division among U.S. voters. According to the Times, his departure is partly a result of company disputes regarding how much to share about nation states manipulating Facebook, and internal restructuring leading up to the 2018 midterm elections.
The company is under fresh scrutiny after media reports that political consultancy Cambridge Analytica harvested private information from more than 50 million Facebook users in developing techniques to support President Donald Trump's 2016 election campaign.More news: Saudi fund said to take $400m stake in Hollywood firm
Facebook said in an emailed statement that Stamos remains the company's chief security officer, without acknowledging any change in his role. He considered leaving in December, when his day-to-day duties were removed, but he was persuaded at the time to stick around until August because executives thought his exit would look bad.

Calls for investigations came on both sides of the Atlantic after Facebook responded to the explosive reports of misuse of its data by suspending the account of Cambridge Analytica.
A Facebook spokeswoman echoed Stamos' sentiment in a statement. When this news broke, Stamos took to Twitter to defend and contextualize Facebook's actions, arguing that the incident did not amount to a "data breach". Stamos left Yahoo in 2015, and Reuters later reported that he left in protest of Yahoo complying with a request from NSA to create scanning technology to comb through users' incoming emails.
Stamos later deleted those tweets, saying he "should have done a better job weighing in". "Nobody is not aware of the risks".More news: Seagal lawyer says sex assault allegations false
