How quickly were MRK trades reported?
Days from each trade to the date its periodic transaction report was filed. The STOCK Act asks members to report a trade no later than 45 days after it happens; a later report is a matter of public record, not by itself evidence of wrongdoing. 42 trades could not be matched to a filing date and are not counted.

| 2023-10-24 | Greg Stanton · D-AZ-04 · House | SellComment: In Sept. 2023, my wife started with a new investment firm for her assets, and this new investment firm was unaware of our policy against owning individual stocks. On Sept. 26, the new investment firm purchased stock mimicking the S & P 500. I learned of the purchase of stock on Oct. 21, and immediately on the next business day (Oct. 23) requested the stocks be divested. The new investment firm sold the stock and instead invested in Exchange Traded Funds. | $1k – $15k | Spouse | 2023-11-09 · 16d | PTR |

Days after the filing date count from the trade to the report; a highlighted figure is past the 45-day deadline. Older trades: the full MRK trade list, or each member’s profile.
What do these records cover?
House trades come from the official House Clerk filings from 2021 on; earlier House rows come from an archive of the same reports. Senate trades come from an archive that ends on Nov 30, 2020. Senators’ MRK trades after that date are not included until the Senate eFD import is live, so this page undercounts Senate activity since then (42 of the 170 trades here are Senate filings). Scanned paper filings are not itemised, so their trades are not counted.
These are trades reported on periodic transaction reports, not current holdings: a member who bought MRK may have sold it since, and a position bought before the records start, or held through a fund, does not show here. Amounts are disclosed as bands. This page is educational and is not a recommendation to buy or sell MRK.
