Actor Jason Alexander, famous for his role as George Costanza on the sitcom Seinfeld, joined in the campaign to raise awareness about the more than 200 hostages who are being held by Hamas.

Alexander recorded a video in which he serves as the voice for nine-year-old Ohad Munder, who celebrated his birthday in Hamas captivity last month.

The Israeli Embassy in the United States thanked Alexander, writing on X, “Thank you, Jason Alexander, for lending your voice on behalf of Israeli hostages held in Gaza by Hamas terrorists.”

AIPAC thanked the actor as well.
