Mr Santos, who labels himself a “former congressional ‘Icon’” on the platform, is selling personalised messages recorded by him for $200 (£159) each.
On Friday, he became the sixth lawmaker in history to be kicked out of the House.
It came after a damning House ethics report accused him of fraud and lies.
Among its many allegations, the panel accused him of spending campaign money on Botox treatments, credit card debt and OnlyFans - a platform where users pay for content, including pornography.
On Mr Santos’s Cameo profile he describes himself as “the Expelled member of Congress from New York City”.
Cameo is a service that allows fans to buy personal video messages from their favourite celebrities.
In the interest of not letting disingenuousness slide:
Pennsylvania Senator John Fetterman posted one video he paid the New Yorker for, in which Mr Santos offers advice to another New Jersey Senator Sen Bob Menendez, a Democrat, who faces bribery charges.
“Hey Bobby,” exclaimed a grinning Mr Santos. “Look, I don’t think I need to tell you, but these people that want to make you get in trouble and want to kick you out and make you run away - you make them put up or shut up!”
He’s still a genocide supporter, but at this point, let’s not stoop to the level of our Congressional “representatives.”
