Wrong.
Read the article.
“No other candidate running for president recorded payments to themselves, FEC files show.”
Are you a Hillary supporter?
I don’t believe no other candidate does this. Current FEC filings are a very long way from having to fully disclose.
It is true that current office-holders *cannot* draw such pay from their campaigns. But even non-incumbent candidates for other Federal offices can draw such pay from their campaigns.
I believe paying themselves and their family and friends is the main reason no-chance candidates stay in the running, although they may prefer to launder the money through family members.
