What is bundling and how is it relevant to recent ethics reforms?

What will be an ideal response?

Bundling is a fund-raising technique. It allows lobbyists to solicit checks from various sources and then give them all at once to a candidate’s campaign committee. This allows them to get around donation limits and also potentially gain more interest from the lawmaker through a large, one-time donation. Ethics reforms in 2007 instituted disclosure requirements on this practice (previously donors using this method were allowed to remain anonymous), but the disclosure requirements are still limited.
