At the center of the scandal is Cambridge Analytica, a political data firm with ties to the Trump campaign. They're accused of accessing, without consent, the profiles of up to 50 million Facebook users and using that information to try to sway your vote.
New video from Britain's Channel 4 shows the "political data firm" giving an undercover reporter a sales pitch and also promising ways to trap rival candidates. Facebook has banned Cambridge Analytica, which says it never used the data and deleted it.

#DeleteFacebook began trending after news of the data leak became public. People were upset their profiles were sold to a company that helped the Trump campaign.
