The Koch Brothers Want to Rewrite the Constitution. They May Succeed.

According to the Center for Media and Democracy, Koch-linked groups have donated nearly $5.4 million to Citizens for Self-Government between 2011, when the group was founded, until 2015, the last year tax records are available. IRS filings show Citizens for Self-Government funding increased from $1.8 million to $5.7 million over that period.
