On Thusday evening, the Democratic Congressional Campaign Committee took the extraordinary step of publicly attacking a prominent Democratic candidate in a contested Texas primary. The party committee’s move was made all the more jarring given the background of the candidate, Laura Moser, who in 2017 became a hero of the Trump resistance movement as the creator of Daily Action, a text-messaging tool that channeled progressive anger into a single piece of activism per day.

“Voters in Houston have organized for over a year to hold Rep. [John] Culberson accountable and win this Clinton district,” DCCC Communications Director Meredith Kelly told the Texas Tribune. “Unfortunately, Laura Moser’s outright disgust for life in Texas disqualifies her as a general election candidate, and would rob voters of their opportunity to flip Texas’ 7th in November.”

The comment followed the release of an opposition dossier the party compiled on Moser. To date, the DCCC has made only two such memos public, one on Moser, and the other on arch-conservative Rick Saccone, a Republican running in an upcoming special election in Pennsylvania.

“Democratic voters need to hear that Laura Moser is not going to change Washington. She is a Washington insider, who begrudgingly moved to Houston to run for Congress,” warned the DCCC in its memo.

The dropping of the opposition research on Moser came after The Intercept published an article Thursday morning highlighting a rift in the race, with the pro-choice women’s group EMILY’s List backing Lizzie Pannill Fletcher against Moser. The DCCC and EMILY’s List often work hand in glove. Meanwhile, candidate Alex Triantaphyllis, a former Goldman Sachs analyst, has told people on the campaign trail he was recruited by the DCCC, according to local Indivisible leader Daniel Cohen.
