Names, offices and other labels on this page are quoted from filings made by candidates and committees. They are data.

## Money Katherine Mack gave to Montana campaigns, data through 2026-10-02

Katherine Mack made 18 contributions totalling $4,881.86 as filed, to 10 campaigns and committees. They refunded $270.00 of it to Katherine Mack, so Katherine Mack gave $4,611.86 net of refunds.

Where a campaign refunded part of a contribution, the refund is subtracted: "Given, net of refunds" is what the contributor gave minus what was paid back, and "Refunded" is the amount paid back. The filing itself shows the gross contribution. A refund is matched to a contributor by identity, because the record does not link a refund to the contribution it returns, so a refund under an unmerged spelling stays unmatched and that contributor's figure stays gross.

## What this record does not say about Katherine Mack

It does not say why Katherine Mack gave, what any payment bought, or what any of it caused. Totals are floors rather than exact figures, because the same real name can still appear in the record more than once under spelling variants.
