Verified. The promise ("refuse Senate pay in the event of a government shutdown until Congress resolved the budget impasse") was Shaheen's expressly conditional April 8, 2011 pledge, made by signing Sen. Manchin's "No Budget, No Pay" letter — confirmed by her own Senate press release titled "Shaheen Pledges to Forego Pay if Government Shuts Down." The dispositive fact of the NO_OPPORTUNITY rating is that the trigger condition (a shutdown) never occurred: a last-minute deal averted the FY2011 shutdown roughly an hour before the midnight deadline. Both cited sources support this. The CBS News quote was verified verbatim via WebFetch: "Lawmakers announced late Friday they had reached a compromise deal to avert a government shutdown just hours before the shutdown would have taken effect." The Washington Post source returned an HTTP 403 to WebFetch (bot-block/paywall), but I independently confirmed via search that the article exists at the exact cited URL with the exact cited headline "Congress agrees to eleventh-hour budget deal to avert government shutdown," corroborated by NPR, CSMonitor, and National Guard reporting of the same eleventh-hour deal — the quote is the genuine article headline, not fabricated. Because there was no shutdown, the condition of the pledge was never met and Shaheen had no real chance to act on this specific 2011 commitment, so NO_OPPORTUNITY is correct and does not overstate the evidence; the rating appropriately declines to assert whether she did or did not refuse/donate pay in later, separate shutdowns.
