Role: Chair, Biden-Harris 2024 Campaign (2023–2024); also served as Biden campaign manager in 2020
Status: Left campaign role after Biden’s withdrawal (July 2024). Later became a senior advisor to Harris’s 2024 campaign. Identified by the DNC’s 2026 post-election autopsy as among top strategists not interviewed for the party’s internal review.
Prior roles: Biden 2020 campaign manager; Obama 2012 national field director

Priority: P2

Tracked Activities: Led post-debate damage control operation; issued memo falsely claiming debate had “no tangible impact”; participated in DNC post-debate call that largely ignored Biden’s performance; cited false campaign finance regulations to discourage donors from pressuring Biden to withdraw; was Biden’s final conversation before his withdrawal announcement.

Background

Jen O’Malley Dillon is a leading Democratic political strategist. She managed Biden’s successful 2020 presidential campaign and was named Chair of the Biden-Harris 2024 reelection campaign — the senior-most campaign official below Biden himself.

After Biden’s withdrawal on July 21, 2024, she transitioned to the Harris campaign as a senior advisor, and was the final person Biden spoke to before announcing his withdrawal (per the Washington Post’s contemporaneous reporting).

Documented Actions

1. The Post-Debate Memo — “No Tangible Impact”

On June 29, 2024 — two days after Biden’s catastrophic debate performance — O’Malley Dillon issued a campaign memo titled “The View From The Battlegrounds” that was distributed to media, party officials, and Hill Democrats. The memo stated:

“On every metric that matters, data shows it did nothing to change the American people’s perception, our supporters are more fired up than ever, and Donald Trump only reminded voters of why they fired him four years ago and failed to expand his appeal beyond his MAGA base.”

The memo acknowledged that polling might shift but pre-emptively blamed any such shift on the media’s “overblown narratives” rather than Biden’s performance:

“If we do see changes in polling in the coming weeks, it will not be the first time that overblown media narratives have driven temporary dips in the polls.”

This memo was circulated simultaneously with the DNC’s post-debate call (chaired by Jaime Harrison) — a coordinated message aimed at stabilizing the party apparatus and donor community at the precise moment both needed accurate information to make decisions about whether Biden should continue.

Within three weeks, Biden withdrew from the race.

2. False Campaign Finance Claims

According to reporting by Lindy Li (former DNC National Finance Committee member), O’Malley Dillon and co-chair Julie Chavez Rodriguez told donors that Biden “could not drop out due to campaign finance regulations.”

This was false. Campaign finance law does not prevent a candidate from withdrawing — as Biden himself demonstrated when he withdrew on July 21, 2024, without legal incident. Federal law provides mechanisms for transferring funds when a candidate withdraws, including to the party and in some cases to the new nominee.

By citing false legal constraints, campaign leadership created an artificial sense that withdrawal was impossible — suppressing donor and party pressure at a critical decision point.

3. Biden’s Final Phone Call

The Washington Post reported that on July 21, 2024 — the day Biden announced his withdrawal — Biden spoke one-on-one with Jen O’Malley Dillon before making his announcement. She was one of only a handful of people Biden directly consulted on his final decision.

This establishes that O’Malley Dillon had senior, trusted status with Biden at the moment of withdrawal — making her simultaneous role in the post-debate damage control effort even more consequential.

4. Excluded from DNC Post-Mortem

The DNC’s 2026 post-election autopsy — despite being described as a comprehensive review of the 2024 loss — notably did not interview O’Malley Dillon, Mike Donilon, Anita Dunn, Steve Ricchetti, or Bruce Reed. CNN reporting on the autopsy noted that these top campaign and administration officials were absent from the review.

This absence means the Democratic Party’s own internal accountability process failed to interview the individuals most responsible for the 2024 campaign decisions.

Political Context

O’Malley Dillon’s conduct sits squarely in the realm of political accountability, not criminal conduct. Running a campaign, managing post-debate messaging, and advising on candidate decisions are all protected political activities. The accountability question is whether the campaign’s senior leadership actively deceived donors, party officials, and the electorate about the viability of their candidate at a moment when the party needed accurate information to make decisions.

What a TRC would investigate: Whether the post-debate messaging campaign — coordinated between the Biden campaign and the DNC — constituted an institutional suppression of information that prevented Democratic stakeholders from acting on accurate data about Biden’s viability.
