Spend over time
Every filing period on record, as reported. One column per filed period — a period with no column is a period with no filing, not a zero.
Basis · Amendments and terminations supersede the original report for the same registrant, client and period, so a revised quarter is counted once at its latest filed value. Registration-only filings carry no activity money and are excluded from these totals.
Who lobbies for them
Every outside firm that has filed on this client's behalf, by fees reported.
Reading this · LD-2 reports a hired firm's fee and a registrant's reported expenses on separate lines and never both on one filing, so the two lists above are different quantities and are ranked separately rather than against each other. Firm names link to their own record as the firms chapter lands.

How these are found · Bill references are extracted from the free-text activity description each filing writes, then matched to the Congress in session that filing year. A reference we can't match to a bill on file is still shown, unlinked — we cite what the filing said rather than guess at what it meant. Naming a bill is not a position on it: LD-2 records that a client lobbied on the bill, never which side.

The filings
Every filing on record. Each row links to its full disclosure.
This record groups every filed spelling of the client's name into one entity, so "MERCK & CO., INC." and "MERCK & CO INC" read as the same company. The grouping is the client's normalized name — organizations that file under genuinely different names appear separately. Handle: lantheus.
