Who Is America: Sheriff Joe Arpaio tells Sacha Baron Cohen he’d accept oral sex from Donald Trump

The Republican Senate candidate also lectures a toy doughnut on the benefit of guns

The latest episode of Who Is America? saw the reported appearance of former Arizona Sheriff Joe Arpaio - and it was as controversial as you'd expect.

Sacha Baron Cohen introduced a brand new character in the fourth instalment of his comedy series which continues to dupe political figures into performing controversial acts.

He welcomed Arpaio onto a chat show hosted by eccentric Finnish YouTuber OMGWhizzBoyOMG during which the Republican Senate candidate - pardoned by Trump in 2017 after being charged for his extreme racial profiling in the US - lectured a toy doughnut on the benefits of guns.

Cohen's character - who revealed he bought 43 guns in preparation for the "upcoming race war" - was told by Arpaio that Trump would be a fan of his ideas.

The most striking moment, however, came towards the end of the interview when Cohen's character asked Arpaio if he'd accept a blow job from the president to which he replied: "I may have to say yes."

Arpaio became aware he was duped by the Borat funnyman following Sarah Palin's realisation. H told The Arizona Republic he believed OMGWhizzBoyOMG to be a famous journalist and sat through it despite the questions "zeroing in on sex."

Other disturbing moments in the fourth episode saw conservative activist Shaun McCutcheon transform his office into a "mosque" in a bid to defend himself from potential terrorist harm.
