Google fires AI ethics founder Margaret Mitchell

In a statement, Google said an investigation found Margaret Mitchell had moved files outside the company.

The ethics unit has been under scrutiny since December, following the departure of another senior figure, Timnit Gebru.

Both women had campaigned for more diversity at Google and raised concerns about censorship within the company.

Dr Mitchell announced the news in a tweet, which read "I'm fired".

For the past five weeks she had been locked out of Google's systems, including her emails and calendars.

James Gunn: Guardians of the Galaxy director fired over offensive tweets

The American filmmaker apologised after old tweets in which he appeared to joke about paedophilia and rape were unearthed and widely shared.

But Walt Disney Studios Chairman Alan Horn announced his sacking on Friday.

"The offensive attitudes and statements discovered on James' Twitter feed are indefensible," he said in a statement.

"[They are] inconsistent with our studio's values, and we have severed our business relationship with him."
