Facebook will remove all messages in which claims are made about the identity of the whistleblower whose information forms the basis of the current settlement procedure against President Trump.

The right-wing news site Breitbart published information about the suspected whistleblower's identity this week. Since Wednesday evening this article is no longer accessible on Facebook, and people who click on the link on Facebook get the message that it is "not available".

In a statement, Facebook states that mentioning the name of the whistleblower violates its internal rules. They prohibit the publication of the identity of "eyewitnesses, informers and activists". Facebook will "remove all entries from the name".

The whistleblower revealed earlier this year that President Donald Trump had put pressure on Ukrainian President Volodymyr Zelensky during a telephone conversation. Trump wanted Zelensky to conduct a corruption investigation into his potential counter-candidate Joe Biden and Bidens son Hunter.

In recent days, several Republican politicians have insisted on disclosing the whistleblower's identity.
