Griffin has been a controversial character since breaking into show business. A comic by trade, she hasn’t been afraid to speak her mind publicly (particularly as it pertains to the current President). Griffin has made appearances on a number of television shows (including her own reality show for a few years). On Seinfeld, she played the roommate of George’s then-wife, Susan.
