Donald Trump's former chief strategist Steve Bannon has been arrested on fraud charges.
The charges are in relation to a fundraising campaign to build a wall on the US-Mexico border, which raised $25 million.
Bannon and three others are accused of defrauding "hundreds of thousands of donors" and taking some of the money for their own personal use.
Donald Trump has denied any knowledge of the project and claims to have had no contact with Bannon for a long time.
Marion McKeone joined us with more detail on the situation.
