All three cited sources are reachable and each documents THIS promise's outcome; every quoted passage was confirmed verbatim. (1) Hawley's own Senate release (PRIMARY, Dec 17, 2024) shows he AUTHORED and unveiled a proposal containing all three promised features verbatim: "Increase the maximum value of the CTC to $5,000 per child, up from $2,000," "Allow parents to use the CTC to offset their payroll tax liability, in addition to income taxes," and receiving the CTC "as regular installments throughout the year." Because this is his own office originating his own proposal, it is genuine leadership (authored/led), not a mere vote or generic support — satisfying the CHAMPIONED bar. (2) The Washington Examiner article confirms the exact quote "I'd like to take it to $5,000, but any incremental increase would be tremendous," and describes Hawley as "long an advocate for a bigger child tax credit" actively pushing during the GOP tax-bill fight — evidencing sustained advocacy, not a single vote. (3) Wikipedia on OBBBA confirms the enacted law raised the CTC only from $2,000 to $2,200 with no payroll offset and no installments, so the substantive $5,000 goal failed in that vehicle. CHAMPIONED correctly captures that Hawley led the promised "push" with the exact features while the full policy was not enacted; FULL would overstate (goal not achieved) and PARTIAL would understate the authorship-level leadership. Outcome upheld.
