The answer

For a member of Congress or federal candidate, go to FEC.gov's individual contributions search (fec.gov/data/receipts/individual-contributions)1 for the raw itemized records, or OpenSecrets.org's member profile page for a pre-organized summary with industry and top-donor breakdowns.2 This works well for federal candidates, since itemized disclosure above $200 per cycle is a legal requirement. It does not show money spent independently on a candidate's behalf by outside groups, including dark-money nonprofits that don't have to name their donors.

Before you go

  • Know whether your representative is federal, House or Senate, covered by the FEC, or state and local, not in the FEC's system. See the companion guide on tracing money in a local race for the latter.
  • Have the exact name of their campaign committee if possible. FEC and OpenSecrets both index by committee, and common names can return multiple candidates.
  • Decide what you want: a quick summary, use OpenSecrets' Donors tab and industry breakdown, or the raw check-by-check record, use FEC.gov's browse tool.
  • Understand the $200 threshold. Contributions below $200 aggregated per cycle from one person don't have to be itemized by name, so small-dollar donors are undercounted in any name-level search.3

The mechanics

  1. Go to fec.gov/data and search the candidate's name, or go directly to their committee page if you know it.
  2. Use the "Individual contributions" browse tool (fec.gov/data/receipts/individual-contributions) and filter by recipient committee, then further by contributor name, city, state, employer, or occupation.4
  3. Each itemized row shows contributor name, city, state, zip, listed employer and occupation, date, amount, and the cumulative amount that contributor has given the committee in the cycle.3
  4. In parallel, open the candidate's OpenSecrets.org profile page (opensecrets.org/members-of-congress, or search their name) and check the Donors tab, which rolls up contributions by organization and employer and by industry sector rather than showing every individual check.2
  5. Check the same profile for a Bundlers section if one exists. FEC rules only require disclosure of bundled contributions when the bundler is a registered federal lobbyist, so this tab will be incomplete for non-lobbyist bundlers.5
  6. To see what wasn't disclosed to the candidate directly, check whether outside groups, super PACs, 501(c)(4)s, spent on the race. OpenSecrets' dark money and outside-spending pages track this at the race or cycle level, though 501(c)(4) donor names are typically unavailable by design.6

What to look for

Repeated donations from the same employer or industry, especially clustered around a relevant committee vote or bill. A concentration of donors outside the district or state. And the gap between what the candidate's own committee disclosed and what outside groups spent on the race. OpenSecrets' industry-breakdown view is built for exactly this: it shows which sectors are the largest source of a member's itemized funding for the current cycle or across their full career since 1989.2

What happens next

A donor list alone doesn't prove influence. Pair it with what you already know: committee assignments (a member on a committee that regulates an industry is a common target for that industry's contributions), recent votes, and any public statements. If the donor list looks thin relative to known spending on the race, check outside spending and dark-money trackers rather than assume the full financial picture has been disclosed.

Does it work

The $200 itemization threshold and required fields (name, employer, occupation, date, amount) are defined directly in the FEC's own data file description.3 The dark-money gap is well documented: 501(c)(4) nonprofits face no general legal requirement to disclose donors,6 and the Brennan Center's tracking found dark money reached a record $1.9 billion in the 2024 federal cycle, up from $1 billion in 2020, while noting this figure likely understates the true total.7 This lookup path, FEC plus OpenSecrets, only covers federal representatives. State legislators, governors, and local officials aren't in the FEC system at all, and every state sets its own contribution limits and disclosure thresholds, so a technique that works nationally for a member of Congress may not translate directly to a state search interface.
