After registration, committees file regularly with the FEC. Those reports are made available in the campaign finance data section of this website.
A committee’s obligation to file regular financial disclosure reports continues until the committee requests to terminate and that request is approved by the FEC.
How to file
Senate candidates and committees can fill out any form (web or PDF) but must file by paper with the Secretary of the Senate.
With the exception of mandatory electronic filers, House candidates and committees can choose whether to file electronically or by paper. They file with the FEC.
