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.
That played out exactly like I thought it would. You had Republicans saying that they were voting him to stay in the House because of his constituents etc then you had other Republicans saying that they were voting him out because he is corrupt etc.
Pretty funny he turned to this, will be entertaining to see where he ends up next.
