London (CNN) The Twitter account of US President Donald Trump on Wednesday retweeted three inflammatory videos posted by the deputy leader of the UK far-right group Britain First. Here's what we know about it.

Founded as a political party in 2011, Britain First is an ultra-nationalist organization that opposes immigration and claims to have "a proven track record of opposing Islamic militants and hate preachers."
