In the second episode of the Showtime special, Cohen takes on the role of Israeli anti-terror expert Captain Erran Morad and enlists Georgia State Representative Jason Spencer, a Republican, to take part in anti-terrorism training.
"There is no excuse for this type of behavior, ever, and I am saddened and disgusted by it," he added.
In a statement to the Atlanta Business Chronicle, Georgia House Speaker David Ralston said Spencer needed to offer his resignation.
"The actions and behavior used on this video are reprehensible," Ralston wrote. "Representative Spencer has disgraced himself and should resign immediately. Georgia is better than this."
According to the Chronicle, Ralson is discussing the possibility of filing a joint ethics complaint against Spencer with House Majority Leader Joe Burns and House Minority Leader Robert Trammell. The Georgia chapter of the Council on American-Islamic Relations is also calling for Spencer's resignation.
Responding to the critiques, Spencer released his own statement on the show, saying that Cohen has taken advantage of him.
"Sacha Baron Cohen and his associates took advantage of my paralyzing fear that my family would be attacked," Spencer to the Atlanta Journal Constitution. "In posing as an Israeli Agent, he pretended to offer self-defense exercises. As uncomfortable as I was to participate, I agreed to, understanding that these ‘techniques' were meant to help me and others fend off what I believed was an inevitable attack."
The "paralyzing fear" that Spencer is referring to is death threats he received for his anti-mask bill that would have barred women from wearing burkas on public property. He ultimately withdrew the legislative proposal.
"I deeply regret the language I used at his request as well as my participation in the ‘class' in general. If I had not been so distracted by my fears, I never would have agreed to participate in the first place," he continued. Spencer concluded his statement by offering more apologies and indicating that he would be finishing up his remaining five months and would then "vacate my seat."
Cohen, who seized the spotlight with the successes of his past undercover projects such as "Da Ali G Show" and "Borat" in the early 2000s, targeted a slew of politicians for his latest endeavor. The show's first episode filmed several officials, including former Illinois Republican Rep. Joe Walsh, for a video message to support a fake program to arm elementary-aged children.
