Rep. Madison Cawthorn just violated a federal conflict-of-interest law, the STOCK Act, for the third time this year.
Cawthorn in January sold up to $50,000 in Let's Go Brandon coin, a cryptocurrency, but waited months to disclose it.
The House Ethics Committee recently fined Cawthorn $15,000 for purchasing the cryptocurrency on terms more favorable than available to the public.
Cawthorn's latest personal financial disclosure, mandated by federal law, shows he sold an amount of "Let's Go Brandon" coin valued between $15,001 and $50,000 in January.
He waited until earlier this month to report the trade, in violation of the federal Stop Trading on Congressional Knowledge Act of 2012.
