The mention of Buttigieg and his fundraising was not a part of a typical Bernie Sanders stump speech, and came as both Sanders and Buttigieg have claimed victory in Monday's Iowa Caucuses, which were beset by an ongoing vote counting debacle.
Recent polling in New Hampshire has clearly shown a bump for Buttigieg in the Granite State, putting forth the same type of outcome in Iowa - where Sanders and Buttigieg were neck and neck for the lead, while Elizabeth Warren trailed far back in third, just ahead of Joe Biden, who has lost ground in those same surveys.
Buttigieg declared victory after midnight on Iowa Caucus night, while Sanders waited until Thursday in New Hampshire to do the same.
Final results from Iowa may not be ready before New Hampshire voters go to the polls on Tuesday.
While Sanders continues to lead in the New Hampshire polls, the numbers have also shown a clear decline for Biden, as he duels with Warren for third, far back of Sanders and Buttigieg.
"I am doing in New Hampshire what I've been doing for a year all across this country," Warren told reporters after a rally in Derry on Thursday, as she parried repeated questions about whether she needed something above a third place finish in New Hampshire, next door to where she lives in Massachusetts.
Meanwhile, Biden continued to be absent from the campaign trail on Friday.
After a morning event in New Hampshire on Wednesday, Biden had no campaign gatherings scheduled until a get out the vote rally in Manchester on Saturday morning.
