A name has been widely circulated on Twitter, with the US president's son, Donald Trump Jr, among those sharing it.

Axar.az reports citing SkyNews that Facebook is deleting the name of the alleged whistleblower who triggered Donald Trump's impeachment inquiry.

The company says any mention of it violates its "coordinating harm policy", which prohibits material that could identify a "witness, informant, or activist".

The policy is not new - Facebook has been removing the person's name for days.

On Friday, the name was widely circulated on Twitter - with the US president's son, Donald Trump Jr, writing a post that included a link to an article which identified the alleged whistleblower.

The whistleblower claims Mr Trump abused the power of his office to "solicit interference from a foreign country" in the 2020 US election.

In a statement, Twitter said it prohibits the sharing of "personally identifiable information about any individual, including the alleged whistleblower".
