Rep. Madison Cawthorn (R-N.C.) is already exiting the U.S. Capitol after losing his seat in this year’s elections, but an ethics investigation unveiled Tuesday will secure something of a legacy for the young congressman: How not to promote cryptocurrency while in Congress.

The House Committee on Ethics released a report on its investigation into Cawthorn’s crypto activity on Tuesday, and it concluded that Cawthorn broke congressional rules in promoting his personal, undisclosed crypto investment and in receiving an improper gift of favorable rates when he acquired his $150,000 in “Let’s Go Brandon” meme coins – named for a phrase meant to be translated as “F*** Joe Biden.”

The panel’s investigative subcommittee “found substantial evidence that Representative Cawthorn promoted a cryptocurrency in which he had a financial interest in violation of rules protecting against conflicts of interest.”
