CapitolRadar analysis
61 trades, with buys ahead by 3
61 tracked DHR trades were disclosed from January 20, 2022 through June 2, 2026: 32 buys and 29 sells. That is a narrow three-transaction difference, with buys representing about 52% of the activity and sells about 48%. The record covers Danaher Corporation, classified in Healthcare / Medical - Diagnostics & Research.
1 distinct trader accounts for the entire tracked sample: Ro Khanna. Khanna disclosed all 32 buys, with the latest dated June 2, 2026. Because every trade comes from one person, the 61 transactions should not be interpreted as a broad measure of congressional sentiment. The transaction count is substantial relative to many single-trader records, but the trader sample itself is very small and fully concentrated.
11 trades across the listed quarterly snapshots
5 trades appear in the listed 2024 quarters: two buys in Q1, one buy in Q2, one sell in Q3 and one buy in Q4. The listed 2025 quarters contain four trades: Q3 had three transactions, including one buy, while Q4 had one buy. In 2026, Q1 recorded one sell and Q2 recorded one buy. These quarterly figures cover only the quarters supplied here and therefore do not account for all 61 trades across the full tracking period.
6 co-purchased tickers, all tied to the same buyer
1 buyer also bought each of ACGL, AMZN, BR, COO, EME and GOOGL. Since DHR has only one identified buyer, these overlaps describe that individual trader’s disclosed activity rather than a pattern shared across multiple buyers.
Congressional transaction disclosures can be filed up to 45 days after a trade, so reported activity may lag the underlying transaction date. Disclosed dollar amounts are typically presented as ranges and should be treated as estimates; no transaction-value ranges are provided in this dataset. The single-trader sample and incomplete quarterly listing further limit broader conclusions.
