#NoBillNoBreak apparently runs on Dunkin'.
Senator Elizabeth Warren of Massachusetts was seen hauling boxes and bags of treats from Dunkin' Donuts down the halls of the US Capitol to help fuel the House Democrats' sit-in, which has been taking place since late Wednesday morning.
"Massachusetts knows: America — and #NoBillNoBreak — runs on @DunkinDonuts," Warren tweeted with a photo on Wednesday night.
Upon entering the room, Warren reportedly announced she brought snacks, and received cheers and applause.

The company has undeniable Boston roots: the first Dunkin' Donuts was founded in Quincy around 1950, and its headquarters are currently located in Canton.
Warren earlier tweeted a photo from the House floor and said there was nowhere she would rather be on her 67th birthday.
Warren also recently took part in a Senate filibuster to spur a vote on gun control measures.
The protest — over bills blocked by House leaders that would expand background checks and attempt to prevent suspected terrorists from buying guns — came more than a week after the Orlando nightclub massacre, the country's worst mass shooting in modern history with 49 victims.
House Speaker Paul Ryan, the chamber's top Republican, dismissed the sit-in as a "publicity stunt'' in a CNN interview and said the House GOP had no intention of passing measures that he said would erode gun ownership rights.
