Senator Cory Booker Raises Concerns Over Maine Senate Candidate Platner's Conduct Revelations

On May 31, 2026, Senator Cory Booker of New Jersey appeared on ABC's This Week and was asked whether the mounting controversies surrounding Maine Democratic Senate candidate Graham Platner could "jeopardize Democratic hopes to get that Senate seat." Booker's answer was uncharacteristically blunt: "Yeah, I have concerns. That guy has questions to answer. And that's what campaigns are for." [1]

The statement marked the most prominent national Democrat to publicly distance himself from Platner, a 41-year-old oyster farmer and Marine Corps veteran whose campaign to unseat Republican Senator Susan Collins has been engulfed in a series of escalating scandals. With the Democratic primary just nine days away on June 9 and Platner widely expected to win it, the party faces a question with no easy answer: what to do about a candidate who leads in the polls but trails a growing cloud of misconduct allegations.

The Revelations: A Timeline of Compounding Scandals

The controversies surrounding Platner have arrived in waves, each one building on the last.

The Reddit posts (Fall 2025): National and local news outlets reported on now-deleted Reddit posts attributed to Platner spanning nearly a decade. Among the most inflammatory was a comment mocking a wounded soldier injured during a Taliban ambush in 2012. Platner's post read: "This video never gets old. Dumb motherf****r didn't deserve to live." [2] Other posts downplayed sexual assault, used homophobic slurs, and made crude comments about sex workers [3]. Three campaign officials, including political director Genevieve McDonald, resigned in October 2025 amid the fallout [4].

The Nazi-linked tattoo (Early 2026): Platner acknowledged having a chest tattoo resembling the SS Totenkopf, a skull-and-crossbones symbol associated with the Nazi Schutzstaffel. He said he got it during a night of drinking while stationed in Croatia in 2007 and claimed he did not know its meaning at the time. However, reporting from WGME suggested that Platner's own past Reddit posts indicated awareness that the design resembled Nazi imagery [5]. He had the tattoo covered up earlier this year. Representative Jim McGovern (D-MA) called the tattoo "disqualifying," while Representative Seth Moulton (D-MA) defended Platner, saying the candidate had "taken responsibility for it" [6].

The sexting revelations (May 30–31, 2026): The Wall Street Journal and New York Times reported that Platner had exchanged sexually explicit text messages with multiple women. His wife, Amy Gertner — whom he married in 2024 — had discovered the messages on his phone in late summer 2025 and flagged them to a member of his campaign staff [7]. TMZ subsequently reported on Gertner's response; she called the media coverage "shameful" and framed the issue as a private marital matter [8].

The whistleblower intimidation allegation (May 31, 2026): The Bangor Daily News reported that Morris Katz, a strategist with the Platner campaign, threatened former political director Genevieve McDonald through an intermediary after she spoke to the Wall Street Journal and New York Times about the explicit texts. According to McDonald, Katz demanded she call the WSJ, retract her comments, tell them their reporting was inaccurate, and send him a recording of the call. When she refused, Katz wrote that if "the story goes in its current iteration we'll communicate directly on the record, and by name, that Genevieve violated the personal trust of Amy and Graham and shared explicit falsehoods to sabotage the campaign." [4]

Democratic Responses: A Party Divided

Booker's public "concerns" did not come in isolation. Several Democrats had already begun distancing themselves from Platner in the preceding weeks, particularly after the tattoo and Reddit revelations. Fox News reported that top Democratic officials and lawmakers were "breaking with" the Maine candidate as his controversies mounted [9].

But the party response has been fractured rather than unified. Senator Chris Murphy (D-CT) told CBS News that Platner has "made mistakes" but framed the race as "between somebody who has spent his life protecting us versus somebody who seems to be protecting Donald Trump's corruption" [10]. Senator Ruben Gallego (D-AZ) endorsed Platner earlier in the campaign, as did Senator Bernie Sanders (I-VT), though the endorsements preceded the most recent revelations [11].

Booker himself stopped short of calling for Platner to withdraw. His formulation — "that's what campaigns are for" — left the door open for Platner to address the allegations and continue running. This calibrated ambiguity has drawn criticism from multiple directions.

The Political Stakes: Why Maine Matters

The Maine Senate seat is one of Democrats' top two pickup opportunities in 2026, alongside North Carolina. The current Senate stands at 53 Republicans and 47 Democrats (including two independents who caucus with Democrats). Democrats need a net gain of four seats to retake the majority [12].

Collins, 73, is seeking a sixth term and is widely considered the most vulnerable Republican incumbent. Despite her reputation for bipartisan moderation, she has faced sustained criticism from the left for her vote to confirm Supreme Court Justice Brett Kavanaugh and her support for the 2017 Tax Cuts and Jobs Act.

Polling has consistently shown Platner leading Collins. A University of New Hampshire survey released May 27 found Platner ahead by nine points, 51% to 42% [13]. An earlier May poll showed a seven-point lead, 48% to 41% [14]. The gender gap is stark: women backed Platner over Collins 53% to 34%, while men favored Collins 47% to 44% [13].

Maine's broader electoral landscape favors Democrats. The state backed Joe Biden by roughly nine points in 2020, and Collins won reelection that year by a smaller margin than expected, benefiting from ticket-splitting. Maine also has an independent streak — Senator Angus King caucuses with Democrats as an independent — and ranked-choice voting in federal elections, which tends to benefit candidates with broad appeal.

Yet Collins has a documented history of outperforming her polls. In 2020, most surveys showed her trailing Democrat Sara Gideon, and she won by nearly nine points. Republican strategists argue the same dynamic could repeat if Platner's scandals erode his favorability among moderate and independent voters.

The Candidate: Who Is Graham Platner?

Platner, born September 1, 1984, grew up in coastal Maine. He attended the Hotchkiss School in Connecticut and John Bapst Memorial High School in Bangor before enlisting in the Marine Corps after graduation [15]. He served eight years, including three combat tours in Iraq and one in Afghanistan with the Maryland Army National Guard. After his military service, he worked as a State Department security contractor in Afghanistan before returning to Maine in 2018 to become an oyster farmer [15].

He entered the Senate race as a progressive populist, running on economic themes and his military service. His candidacy drew comparisons to other unconventional Democratic veterans who have run for office in recent cycles. Press Herald reported that Platner was outraising and outspending Collins as of late May [16].

The Democratic primary initially featured a competitive field. Maine Governor Janet Mills entered the race, setting up a contest between the party's centrist establishment wing and its progressive flank. But Mills suspended her campaign on April 30, 2026, clearing Platner's path [17]. His remaining primary opponent, David Costello — a former Maryland government staffer who ran unsuccessfully for Angus King's seat in 2024 — has not polled competitively [18].

Can Democrats Replace Platner?

The question that has moved from hypothetical to practical: if Platner wins the June 9 primary, can the party swap him out?

Under Maine law (Title 21-A, §374-A), a candidate who wins the primary and subsequently withdraws by 5 p.m. on the second Monday in July may be replaced by a nominee selected by party officials. Any replacement must be chosen no later than 5 p.m. on the fourth Monday in July [19]. This provision has received increasing attention from political commentators and party strategists.

The Washington Examiner reported that Democrats have been exploring this mechanism as a contingency [20]. PJ Media noted that some Democrats believe the party "should have listened to Chuck Schumer," suggesting the Senate leader may have privately expressed reservations about Platner's candidacy earlier [21].

However, replacing a primary winner is politically fraught. Platner's supporters — particularly in Maine's progressive grassroots — would view such a move as establishment overreach. The Platner-Mills contest was already seen as a proxy fight between the party's populist and centrist factions; replacing the populist winner with a party-selected alternative would risk alienating a significant portion of the Democratic base in a state where independents and progressives hold outsized influence.

Historical precedent offers limited guidance. In 2002, New Jersey Democrats replaced Senator Robert Torricelli with Frank Lautenberg after Torricelli withdrew amid a corruption scandal, though that case involved a candidate stepping aside voluntarily. In Missouri in 2000, Governor Mel Carnahan's name remained on the ballot after his death in a plane crash, and his widow was appointed to serve after he posthumously won. Neither situation precisely mirrors a party overriding a living, unwilling candidate.

The Steelman for Platner's Defenders

Supporters of Platner argue that his personal failings, however objectionable, should be weighed against the political stakes. The explicit texts are a matter between Platner and his wife, they contend, and the Reddit posts and tattoo reflect a younger version of a man who has since served his country in combat and built a life as a small business owner.

Moulton's defense — that Platner has "taken responsibility" — reflects this view [6]. Murphy's framing of the race as a choice between a veteran and a Collins who has backed Trump's agenda attempts to redirect the conversation to policy [10]. Platner's supporters also note that the timing of the revelations — arriving weeks before the primary — suggests opposition research rather than organic journalism.

More broadly, Platner defenders see Booker's intervention as a case of the national party establishment inserting itself into a state race based on allegations that have not been adjudicated in any legal proceeding. Maine Democrats chose Platner in large numbers; polls show he would beat Collins. Overriding that choice, they argue, would be anti-democratic.

The Steelman for Booker's Critics from the Left

From the opposite direction, some on the left have criticized Booker for not going far enough. If the sexting allegations — and particularly the campaign's alleged intimidation of a whistleblower — are serious enough to warrant "concerns," why not call explicitly for Platner to step aside?

The gap between expressing concerns and demanding withdrawal, critics argue, reflects political calculation rather than principle. Booker — who gained national prominence through his record-breaking 25-hour Senate floor speech protesting the Trump administration in April 2025 [22] — has positioned himself as a moral voice within the party. Stopping at "concerns" while acknowledging "so much is riding on Democrats taking control of the Senate" suggests the political arithmetic is doing as much work as the ethical judgment.

If the allegations involve harm to individuals — the women who received unsolicited explicit messages, the former staffer who was allegedly threatened — then the hedged language looks less like genuine ambiguity and more like risk management. The question for the left is whether a party that claims to take misconduct seriously can simultaneously weigh it against electoral convenience.

What Happens Next

The June 9 primary will almost certainly produce Platner as the Democratic nominee, absent a dramatic reversal. What follows will test the party's cohesion and its willingness to use the legal mechanisms available under Maine law.

The scandals show no sign of subsiding. The Bangor Daily News reported that Platner avoided questions about the sexting revelations at a Maine campaign event on May 31, and that his staffers physically blocked journalists attempting to ask about the controversy [23]. Collins's campaign and the National Republican Senatorial Committee have signaled they intend to make Platner's personal conduct a central issue in the general election [9].

For Democrats, the Maine seat represents both one of their best opportunities and one of their greatest vulnerabilities in the 2026 cycle. The party must decide whether the risk of running Platner — with his polling lead but compounding baggage — is greater or lesser than the risk of replacing him and facing a fractured base, a compressed timeline, and the appearance of backroom dealing in a state that values political independence.

Booker's "concerns" may have been carefully worded, but the situation they describe is anything but careful. It is messy, urgent, and unresolved — and it will shape not only the Maine Senate race but the broader Democratic calculus for control of the chamber.
