How to read this page

Registration type, direct contributions, and outside spending are different.

A committee can contribute directly to candidates, make independent expenditures, transfer money, or do some combination permitted by its registration. Election.org keeps those categories separate and does not infer support, opposition, coordination, or control from a name alone.
