A person dressed in a black top hat and bushy white mustache sat in the audience of the Senate's Equifax hearing on Wednesday.
The Monopoly guy impersonator, who periodically dabbed their forehead with giant paper money throughout the hearing, immediately gained popularity on Twitter.
In the hearing, Former Equifax CEO Richard Smith testified about a data breach that compromised personal information for more than 145 million people.
The Monopoly impersonator was allegedly part of a protest by a group that wants to draw attention to arbitration clauses that are used throughout the financial industry and limits consumers' ability to take disputes to court.
The protester Amanda Werner issued a statement to USA Today about the protest.
"Arbitration is a rigged game," Werner said in an emailed statement to USA Today. "Bank lobbyists and their allies in Congress are trying to overturn the CFPB's rule so they can continue to rip off consumers with impunity."
