Sacha Baron Cohen’s new Showtime series, “Who Is America?,” caused a stir before its premiere last week, as several Republican politicians felt the need to get ahead of the show in explaining how Cohen “duped” them to appear on it.

The former vice presidential candidate Sarah Palin, the former congressman Joe Walsh, and the former US Senate candidate Roy Moore were among those who preceded the show’s premiere with statements explaining their appearances on the series and criticizing Cohen.

In the show’s first episode, Cohen, disguised as an Israeli “anti-terror expert,” roped several Republican congressmen and former elected officials into voicing their support for a program that would arm toddlers with guns to prevent school shootings.

This week, the former vice president Dick Cheney and broadcast journalist Ted Koppel were among the notable people who appeared on the show as unsuspecting guests.

Before the show’s premiere last week, Matt Drudge of The Drudge Report tweeted a list of political and media figures he said Cohen had “finked” for the series, including Palin, Howard Dean, and David Patreus, whom we can expect to see in the show’s subsequent five episodes.
