Pelosi continues to project confidence that she has the votes to be elected speaker and she is still running unchallenged, though Rep. Marcia Fudge of OH has said she is considering entering the race.
Trahan, who beat out a crowded field to win the seat being vacated by fellow Democrat Niki Tsongas, told The Lowell Sun on Friday she has signed a letter backing Pelosi as Democrats prepare to formally retake the chamber in January. Opponents said Monday that they are convinced that it is time to select a new leader.
Pelosi has said she has "overwhelming support" among fellow Democrats to become the next speaker.
On the one hand, Pelosi's supporters say now more than ever the party needs the California Democrat's leadership as a skilled strategist and tireless fundraiser to confront President Donald Trump and Senate Republicans in Congress. That includes Rep. Marcia Fudge of OH, who has said she is considering running for speaker.
Democratic aides involved in the effort to oust Pelosi but not authorized to comment publicly said they are confident additional lawmakers would oppose Pelosi in a floor vote beyond those who signed the letter.
"Our majority came on the backs of candidates who said that they would support new leadership because voters in hard-won districts, and across the country, want to see real change in Washington", the letter from Democrats read.
Another five - Golden, Rep. Conor Lamb of Pennsylvania, and Reps. -elect Jason Crow of Colorado, Mikie Sherrill of New Jersey and Abigail Spanberger of Virginia - have made firm statements saying they would not vote for Pelosi but did not sign the letter.
Pelosi has mocked reports that her leadership would be challenged.
Several high-profile freshmen who have vowed to oppose Pelosi are notably missing from the letter. For numerous Democratic freshmen, it's a moment of truth after a number of them promised on the campaign trail to oppose Pelosi and demand new leadership. Rep. Tim Ryan (D-Ohio), whose name is on this letter, removed himself from a letter in 2016 that sought to delay leadership elections when he ran against Pelosi for the minority leader position to make it look less like the letter was about his bid for the position.
Pelosi, for her part, has signaled confidence throughout this whole experience that she will be elected.
"Right now she's the only person who's running, so it would appear as though that's where my vote would go", Houlahan said on CBS's "Face the Nation" Sunday.
Her supporters say that after winning hard elections against Trump's campaigning, the Democrats can't afford to get bogged down in a protracted leadership fight ahead of the January 3 vote.
Even with Fudge off and some Democrats shaky, the opposition is still enough at this point to block Pelosi from being speaker. Fudge has said she will decide after Thanksgiving if she is running.
