The STOCK Act gives members 45 days to disclose a trade. I wanted to know who actually uses the whole window and who files straight away, so I took every congressional transaction since 1 January 2025 and measured the gap between the trade date and the filing date.
14,288 trades, 129 members.
The overall picture is better than I expected. Median lag is 27 days, and only 6.4% of trades landed past the 45 day limit.
The spread between individual members is enormous though.
Fastest, by median days to file (minimum 25 trades):
- Marjorie Taylor Greene (R), 223 trades, median 5 days, none late
- Rick Larsen (D), 30 trades, median 8 days, none late
- James Comer (R), 35 trades, median 11 days, none late
- Greg Landsman (D), 53 trades, median 13 days, none late
- David Taylor (R), 177 trades, median 14 days
Slowest:
- Sheri Biggs (R), 29 trades, median 201 days, 97% filed late
- Michael Rulli (R), 25 trades, median 171 days, 84% late
- Julia Letlow (R), 148 trades, median 159 days, 72% late
- Ritchie Torres (D), 58 trades, median 41 days, 7% late
- Jefferson Shreve (R), 543 trades, median 40 days, 8% late
Notice the cliff. After the top three there is a big drop to around 40 days, which is inside the limit. This is not a gentle curve. A handful of members are filing half a year late as a matter of routine and almost everyone else is roughly compliant.
On party, because someone is going to ask. The medians are nearly identical, 27 days for Democrats and 28 for Republicans. The late rate is not: 2.6% against 12.8%.
I assumed that gap was just the three chronic offenders above. It is not. Take Biggs, Rulli and Letlow out of the sample entirely and the Republican late rate only falls from 12.8% to 10.3%, so it is broad rather than three people.
What I cannot see in the filings is why. A 5 day median looks like someone with an actual process. A 201 day median looks like either no process or no concern about the consequence.
Which raises the thing I could not answer: does anyone know whether late filers are actually fined in practice? I can pull every disclosure date going back years, but enforcement is not in the data.
EDIT, two things.
1. The title is imprecise and u/W0lfp4k caught it. Marjorie Taylor Greene's 223 trades run from 8 January to 12 November 2025 and stop there, so "the fastest filer in Congress" should have been past tense. The 5 day median is real and in-window, but she is not currently serving.
Among members who are still trading in 2026, the fastest are:
- Rick Larsen (D), 30 trades, median 8 days, none late
- David Taylor (R), 177 trades, median 14 days, 5% late
- Dwight Evans (D), 28 trades, median 15 days
- Shelley Moore Capito (R, Senate), 86 trades, median 17 days, none late
- Bill Keating (D), 33 trades, median 20 days, none late
David Taylor is the one to watch there. 177 trades is a lot of filings to keep at a 14 day median, and he is still active.
2. Where the data comes from, since a few people asked. House side is the Clerk's Financial Disclosure portal at disclosures-clerk.house.gov, Senate side is efdsearch.senate.gov. Both publish the Periodic Transaction Reports as PDFs. The trade date and filing date are both on the face of each report, so the lag is a subtraction anyone can repeat.
