Source: U.S. Office of Government Ethics. Values reported in ranges per federal law. A trade is listed here only when its printed name was read the same way by two independent readers and matched this security exactly, by symbol or by name on two reference lists, or a person confirmed it. Broker abbreviations still under review are not listed; the trades stay on the official’s page under the printed name.
