Facebook refuses to delete fake Pelosi video spread by Trump supporters

Footage of House speaker deliberately slowed down to make her appear drunk or ill

Facebook says it will continue to host a video of Nancy Pelosi that has been edited to give the impression that the Democratic House speaker is drunk or unwell, in the latest incident highlighting its struggle to deal with disinformation.

The viral clip shows Pelosi - who has publicly angered Donald Trump in recent days - speaking at an event, but it has been slowed down to give the impression she is slurring her words. Several versions of the clip appeared to be circulating.
