The Welcome Party is the Welcome ecosystem's registered 501(c)(4) entity in the current public-page record. In this repository it matters because the captured Promise to America signatory pages, including Jessica Killin's page, are authored by The Welcome Party, and because prior CO-05 work separately identified a Joe Reagan income/title lead tied to The Welcome Party.
- Welcome about-page role: registered
501(c)(4) launched in Fall 2019 to engage less ideological and less partisan swing voters and support big-tent party research and advocacy.
- ProPublica Nonprofit Explorer identity in the retained source:
The Welcome Party Inc, EIN 843511352, subsection code 4.
- Promise to America role in the retained source: author of the signatories index entries and Jessica Killin's candidate/signatory page.
- OpenFEC donor context: The Welcome Party Inc appears as a contributor to WelcomePAC in retained top-amount Schedule A screens.
- The Welcome Party is not interchangeable with WelcomePAC, even though Welcome's public about page places both in the same aligned ecosystem.
- The Welcome Party's authorship of a Promise signatory page supports a public coalition/policy-branding signal. It does not by itself prove PAC spending, candidate coordination, control, sponsorship, influence, or donor money flow.
- The repo's Joe Reagan evidence includes a prior income line and Cause IQ title lead for The Welcome Party. That should not be merged with the Killin Promise evidence or with WelcomePAC spending evidence.

- Whether a primary source can identify who operated or legally sponsored the Promise to America site beyond page-level authorship.
- Whether a direct Promise signatory agreement, candidate questionnaire, or sponsor disclosure exists.
- Whether The Welcome Party had any candidate-service, endorsement, messaging, voter-contact, or fundraising relationship with Killin beyond the public Promise page.
