Biden Aide MISSING After Endorsing Republican

A longtime Democratic operative went on live television, refused to back his own party’s Senate nominee, and got run off social media by his own side within days.

Quick Take

Michael LaRosa, a former press aide to Jill Biden, told C-SPAN viewers he will back Republican Mike Rogers over Democrat Abdul El-Sayed in Michigan’s Senate race.
Angry callers accused LaRosa of “dissing” El-Sayed and said he “might as well be a Republican.”
LaRosa says his break is about values, not party, pointing to El-Sayed’s refusal to distance himself from Hasan Piker’s 9/11 comments.
LaRosa deleted his account after the on-air confrontation, and the Rogers campaign publicly welcomed his support.

A C-SPAN Segment Turns Into A Public Reckoning

Michael LaRosa appeared on C-SPAN’s Washington Journal to talk about the 2026 midterms. Instead of a routine political chat, he faced a wave of angry callers. One asked him directly, “What’s wrong with you?” for backing Rogers over El-Sayed. Another accused him of running “a tag team with your Republican buddy” and said he “might as well be a Republican”.

The exchange did not stay contained to the studio. Clips spread fast online, and within a short window LaRosa’s account vanished from public view. For a man who spent decades working inside Democratic politics, watching his own party’s voters turn on him live, on camera, marked a stark moment. It also raised a bigger question: what exactly pushed him to cross the aisle in the first place?

LaRosa Says This Was Never About Party Loyalty

LaRosa insists his decision is not an ideological conversion. He has said plainly that he has “never supported a Republican in my life” for Senate, White House, or Congress. His objection, he says, is narrower and more personal. He will not back a candidate who stayed silent while an ally excused comments about the September 11 attacks.

The trigger was Hasan Piker, a left-leaning commentator who made remarks about 9/11 that LaRosa found indefensible. LaRosa said he “won’t defend or support anyone who is too cowardly to stand up to extremists” who suggested the mother of his close friend “deserved what happened to her” after she died in the attacks. He tied that failure directly to El-Sayed, saying the candidate would not distance himself from Piker.

LaRosa went further than words. He posted that after “decades of giving my all for Democratic House and Senate candidates,” he would support and financially contribute to Rogers instead, and try to convince other Democrats to follow. The Rogers campaign responded warmly, welcoming him aboard and thanking him for the support as the race heads toward November.

Why This Race And This Fight Matter

Michigan’s Senate contest is drawing outsized national attention, and Rogers, a former Republican congressman, is trying to flip a seat Democrats have held. A defection from inside Biden-world circles, even a symbolic one, gives Republicans a talking point about Democratic disunity heading into a competitive cycle. LaRosa has acknowledged he does not live in Michigan and has no direct stake in the race’s outcome, which limits how much weight his endorsement carries locally, even if it carries weight nationally as a signal.

The reaction LaRosa faced fits a well-documented pattern. Research on political endorsements shows that cross-party statements often provoke stronger backlash from the endorser’s original camp than support from the new one, because they function as identity signals rather than persuasion tools. Studies of endorsement effects found that Democratic voters, for instance, moved further away from candidates once told a Republican figure backed them, showing how quickly loyalty tests override policy substance once a defection becomes public.

That dynamic explains why LaRosa’s specific 9/11 argument barely registered with his critics on the C-SPAN call-in lines. Once a Democrat says he is backing a Republican, the conversation tends to stop being about the reason and starts being about the betrayal. Whether or not viewers agreed with his reasoning, the caller reaction proved his point in a way: plenty of people were more interested in punishing the switch than debating the substance behind it. That reflex, not the endorsement itself, is the more revealing story here.
