Both cited PRIMARY sources were fetched and verified. (1) The Alsobrooks Senate office press release confirms she "joined...in the bicameral reintroduction of the Assault Weapons Ban of 2025" as a co-sponsor (not lead author); the bill "would ban the sale, transfer, manufacture, and import of military-style assault weapons, high-capacity magazines," covering the military-style-weapons/AR-15 promised item. The quoted sentence appears verbatim and is attributed to Alsobrooks. (2) The Murphy Senate press release confirms Alsobrooks is a cosponsor (Murphy leads) of the Background Check Expansion Act, which "expand[s] federal background checks to all gun sales" and "extends to all unlicensed sellers, whether they do business online, at gun shows, or out of their home" — covering BOTH universal background checks AND closing the gun show loophole. The cosponsor sentence appears verbatim. Alsobrooks is thus a documented cosponsor on three of the four promised measures. The fourth item — prohibiting bump stocks — is not supported by either cited source and remains unconfirmed (listed on her platform but no legislative action verified). None of the bills was enacted (Senate minority). Because she is a cosponsor rather than the lead author (no CHAMPIONED-level leadership), acted on three of four measures, bump-stock action is unconfirmed, and nothing became law, PARTIAL is the correct rating — not FULL, ATTEMPTED, or CHAMPIONED. The outcome does not overstate the evidence.
