US ambassador's email to activist sparks police intervention at Brussels event — UnionPress

A letter from US ambassador Bill White to a Belgian‑based activist was copied to Belgian police, leading to the journalist's detention at a Trump‑linked celebration and raising concerns over privacy and intimidation.

Bill White, the United States ambassador to Belgium, sent an email to activist John Hasan Yildiz that was also copied to senior Belgian police officials. The message, which appeared to reference personal data about Yildiz, was followed a few days later by the journalist who reported on the exchange being escorted out of the Freedom 250 celebration organised by Donald Trump's business interests in Brussels.

Yildiz, who co‑founded the Belgian chapter of the American grassroots movement Indivisible, wrote to the Zac Brown Band, the headliner of the event, asking the musicians to reconsider performing at a gathering he described as "political". In his email he noted the band's public support for the military and its usual avoidance of politics, arguing that the celebration of the United States' 250th anniversary was anything but neutral.

Shortly after sending the request, Yildiz received a terse reply from Ambassador White. The email began with a single line, "We know it already", and was copied to Eric Snoeck, commissioner general of Belgium's federal police, Jurgen De Landsheer, chief of the Brussels Midi‑zone police, and Seth Lindenfeld, head of security at the US embassy, among other Belgian law‑enforcement addresses. The message concluded with the same phrase, "Pls do let us know because we know it already". Yildiz interpreted the tone as an attempt to intimidate, saying the correspondence made him feel "under pressure".

When UnionPress journalist Julius and his colleague attended the Freedom 250 event on Sunday, they were invited by the US embassy to cover the ceremony. After the pledge of allegiance and a fly‑over of World War II‑era aircraft, a group of roughly eight plain‑clothed officers approached the two reporters, identified them, and ordered them to leave the venue. The journalists were escorted out of the hall and detained briefly before being released.

According to a spokesperson for Brussels mayor Philippe Close, the city had been informed that the ambassador's own security team had flagged the journalists as an "active threat" to White. The spokesperson added that White had personally ordered the removal, claiming he did not feel "safe". The police, however, acted on instructions from the ambassador's office rather than any independent security assessment, and no US security personnel were present at the scene.

When UnionPress asked Ambassador White to comment on the detention and the earlier email to Yildiz, he responded by conflating the two incidents, referring to the journalists as "losers" and mistakenly identifying the editor‑in‑chief as the activist who had sent the original message. In a subsequent exchange, White accused the journalist of approaching him with a weapon and harassing embassy staff, accusations that the reporter denied.

The email raised questions under the EU's General Data Protection Regulation (GDPR). Data‑protection scholar Pia Groenewolt of the Vrije Universiteit Brussels noted that GDPR permits processing of personal data only for narrowly defined lawful purposes, none of which were cited in White's message. She said the ambassador's vague references to "several" reasons failed to meet the regulation's requirement for a specific legal basis.

European Digital Rights (EDRi) policy adviser Itxaso Domínguez de Olazábal warned that the incident could have a chilling effect on political expression. "When a senior public official brings law enforcement into correspondence with someone over what appears to be lawful political expression, the message is not only received by that individual. It is received by everyone else watching," she said. "Public authorities should never create the impression that they are using information asymmetries or personal data to intimidate people exercising their fundamental rights."

Belgian officials who were copied on the email have either declined to comment or, in the case of De Landsheer's office, confirmed receipt but said no action had been taken. The Belgian foreign ministry also refused to comment, leaving the extent of any formal investigation unclear.

Ambassador White has a history of controversial statements in Belgium. In 2023 the Belgian foreign ministry summoned him after he labelled the country "antisemitic" in connection with a prosecution of unlicensed circumcision practitioners in Antwerp. Flemish prime minister Bart De Wever publicly rebuked White for "constantly stirring things up in domestic politics". Earlier this year White claimed to have barred Conner Rousseau, leader of the Flemish socialist party, from entering the United States, a move De Wever dismissed as "no purpose between allies".

Local Green councillor Benedetta De Marte expressed alarm at the ambassador's conduct, saying, "It is very worrying that the American embassy felt it was completely fine to send this threatening email." She is currently the only Belgian elected official who has spoken publicly on the matter.

Yildiz said he would have welcomed a dialogue with the ambassador, hoping the incident could demonstrate how "conservative leadership can engage progressive voices". He added that the Trump administration's approach, in his view, favours intimidation over conversation.

So far, neither the European Parliament nor the European Commission has issued a statement. Belgian federal and regional leaders have also remained silent, apart from the mayor's office confirming the police action was taken at the ambassador's request.

A petition calling for White's removal as ambassador has gathered more than 2,000 signatures, and thousands of comments on social media have expressed outrage from both Belgian and American observers. Critics argue that the episode illustrates how diplomatic privilege can be misused to target lawful dissent.

Legal experts note that while diplomatic immunity protects ambassadors from prosecution for official acts, it does not shield them from administrative or political repercussions. If a formal complaint were lodged with the Belgian data‑protection authority, the case could be examined under GDPR, potentially resulting in fines or orders to cease the practice of sharing personal data with law‑enforcement agencies without a lawful basis.

For activists and journalists, the incident underscores the precarious balance between freedom of expression and state‑sanctioned surveillance. The use of police resources to enforce the wishes of a foreign diplomat raises questions about sovereignty and the appropriate limits of diplomatic influence within EU member states.

UnionPress will continue to monitor developments, including any official inquiry by Belgian authorities or a response from the US State Department. The episode adds to a growing list of incidents where US diplomatic staff in Europe have been accused of overstepping their remit, prompting calls for clearer guidelines on the interaction between foreign missions and local law‑enforcement bodies.

In the meantime, the Freedom 250 celebration proceeded without further incident, but the shadow of the ambassador's email and the subsequent police action will likely linger in discussions about the role of foreign embassies in European public life.
