Each row is one registrant. The income or expense figure comes from its newest filing, as filed; it is never a total. A client that files for itself is marked self-filed. Each firm opens its own page.

Issue codes are the ones the filer chose from the list set by law. Bills appear as the filings cite them, most-cited first, each linked to its own page where we can match it.

Every row is one filed report from the Senate system. Income and expenses are the registrant's own per-filing estimates, shown as filed; they are never summed here. A blank cell means the filing reported no amount, which the law allows.

A covered position is a prior government job the filing discloses, shown as filed. The law asks only for positions held in the twenty years before the filing, and studies of these filings find them underreported. So a blank means not disclosed. It does not mean the person has no government history. Each name opens the lobbyist's own page.
