Video has emerged of Donald Trump's latest chief of staff describing his new boss as "a terrible human being".

The video of the remarks by Mick Mulvaney was taken during a debate with Fran Person, then his Democrat congressional challenger, in South Carolina less than a week before Mr Trump was elected president in 2016.
