Devin Nunes received about average campaign donations every election of between 1 and 2.5 million. In 2018 he received $12.6 million, nearly 50% of which was <$200 individual contributions and thus do not need to be publicly itemized. He's also already raised 5 million for 2020. People following the impeachment inquiry may know that Nunes and Lev Parnas (Giuliani associate indicted on campaign finance fraud), and that he loudly boasted conspiracy theories during the proceedings.
Devin Nunes is an obvious crook and needs to be investigated immediately.
