The comedian was having lunch at the Polo Lounge when she was noticed she was in the proximity of the former head of CBS.
According to Ramin Setoodeh of Variety, Griffin "loudly asked the waitress to move her, saying: 'I don’t want to be seated next to a rapist.'"
Griffin retweeted the account and added, "Can confirm! I don't like sitting next to rapists."
She later added, "After everything that brave women like @Illeanarama and Linda Bloodworth-Thomason have been through, how disgusting that Les Moonves was just sitting there enjoying his fabulous lunch while so many women have suffered. F**k Him."
Kathy Griffin has been an outspoken leader of the #MeToo movement and recently, in a lawsuit against her neighbor, vowed to give any proceeds from the lawsuit to the Time’s Up Legal Defense Fund.
