Staff who work as part of the company's teams combating dangerous and inauthentic organizations that operate on the platform spoke to CNN on Tuesday.
The staff said the company would take action on people using the platform to organize violence regardless of their political affiliation.
On Monday, Twitter said
a fake Antifa account calling for violence was run by white supremacists. The company removed the account.
The fake account, @ANTIFA_US, tweeted Sunday, "ALERT Tonight's the night, Comrades Tonight we say "F**k The City" and we move into the residential areas... the white hoods.... and we take what's ours #BlacklivesMaters #F**kAmerica."
The account caught the attention of President Donald Trump's son Donald Trump Jr.
"Absolutely insane," Trump Jr. wrote on Instagram, sharing a screenshot of the tweet, "Just remember what ANTIFA really is. A Terrorist Organization! They're not even pretending anymore."
A spokesperson for Donald Trump Jr. did not provide comment to CNN Tuesday morning, but later the post was removed from Trump Jr.'s Instagram feed. There is no indication whatsoever that Trump Jr. knew who was behind the account or that it was fake.
Facebook said Tuesday night it had found some associated accounts on its platforms after Twitter shared information about the fake account — the accounts have been removed from Facebook, the staff said. The accounts had not been used recently, the staff added.
Facebook has come
under intense criticism this week for leaving President Donald Trump's posts on Facebook and Instagram that were labeled on Twitter as glorifying violence.
