Sacha Baron Cohen's Who Is America? is taking no Republican prisoners.

In episode three of the comedian's latest show, Cohen sat down with Roy Moore, former Chief Justice of the Supreme Court of Alabama.

Moore faced a string of allegations of sexual assault while he ran for Alabama State Senate as Republican candidate.

Some accusations, which include claims of inappropriate or unwanted behaviour and groping, came from women who claimed they were minors when Moore assaulted them.

One claimed she was 14 years old when Moore, then in his 30s, initiated a sexual encounter with her.

Moore has also been accused of anti-Semitism after comments suggesting Jewish billionaire George Soros doesn't "recognise God and morality and accept his salvation" and would therefore be going to hell.

Cohen pretended to be an Israeli anti-terror expert for an interview with Moore, who lost the State Senate race.

Boasting about Israel's technological achievements in stopping the Hamas, Cohen's character told Moore of another device that Israelis developed to protect children from sexual predators.

Watch the hilarious clip (between your fingers, if need be) to see what happened when Cohen introduced the "sex offender detector" to Moore.
