Donald Trump spat with Univision 'hurting Republicans'

The fallout from this week's press conference in which US Presidential Candidate Donald Trump expelled a veteran Spanish-language reporter shows little signs of abating.

The video footage of Mr Trump cutting off Jorge Ramos of Univision and having him escorted from the room made headlines worldwide, and angered many in the politically-significant Latin American community.

Arturo Sarukhan is the former Mexican ambassador to the United States; he tells the BBC's Katty Kay that Trump's behaviour is doing little to help Republicans attract Latino voters.
