Both cited PRIMARY sources (Senator Murphy's official Senate office) are reachable and directly support CHAMPIONED for this exact promise. The June 17, 2026 release documents Murphy INTRODUCING the National Strategy for Social Connection Act, which "would create a permanent Office of Social Connection Policy within the White House to work across federal agencies to develop effective strategies to combat social isolation and provide national guidelines for social connection," and also introducing the companion SILO Act — verbatim confirmation of the quoted sentence. The July 25, 2023 release documents endorsing organizations (Meals on Wheels America, Coalition to End Social Isolation & Loneliness, For All Ages) explicitly praising Murphy's "leadership" and "swift action introducing" the bill in response to the Surgeon General's Advisory. This clears the leadership bar for CHAMPIONED: Murphy is the author/lead sponsor who introduced the bill (2023), reintroduced it (2026), and built a supporting coalition — sustained leadership, not a mere vote or expression of support. It is correctly NOT rated FULL because the bill has not been enacted (it remains pending); the promise verb "pursue" is satisfied by authoring, championing, and reintroducing across two Congresses. Both quotes appear on their respective pages and neither is fabricated.
