A letter has been circulated in the European Parliament calling for an investigation into the possible influence of U.S. President Donald Trump’s administration on FIFA’s decision to lift the suspension of American forward Folarin Balogun, Euronews reports.

This came ahead of the World Cup round-of-16 match in which the U.S. national team lost to Belgium 1–4.

On Tuesday, a group of Members of the European Parliament proposed a review of FIFA President Gianni Infantino’s role and whether pressure from the U.S. administration influenced the decision to alter the player’s punishment.

The letter, seen by Euronews, is addressed to the football associations of the 27 European Union member states. It calls on them to formally approach FIFA and demand an investigation into the decision-making process in Balogun’s case.

“We believe the time has come for Europe’s football associations, each of which is a member of FIFA, to step in and ask FIFA to investigate the decision-making processes in the Balogun case,” the document says.

One of the initiators of the letter, MEP Barry Andrews, told Euronews that “once again, we have seen Infantino and FIFA bow to the demands of the Trump administration.” He called the organization’s decision “a disgrace and a perversion of justice.”

Balogun received a controversial red card in the U.S. national team’s match against Bosnia and Herzegovina last week. Under the rules, a sending-off automatically means a suspension for the next match, so he was supposed to miss the game against Belgium — a knockout match.

Trump later confirmed that he had called Infantino about Balogun’s red card, calling the decision unfair, but said he had asked for nothing in return. After that, FIFA suspended the enforcement of the ban, using a controversial legal procedure that had never before been applied at World Cups since the introduction of the red-card system.

Trump later thanked Infantino for “correcting a great injustice.” For his part, the FIFA chief said that during the conversation he had informed the U.S. president about the independence of the organization’s disciplinary body.

FIFA’s decision triggered a sharp reaction in Europe.

The Union of European Football Associations (UEFA) called it “unprecedented, incomprehensible and unjustified,” while the Royal Belgian Football Association launched a formal appeal against Balogun’s eligibility to take part in the match.

European Commissioner for Sport Glenn Micallef also said that lifting the suspension had been “the wrong decision.”

“This runs completely contrary to FIFA’s rules and statutes [...] and is a real scandal,” former UEFA communications and public affairs director William Gaillard said on Euronews’ Europe Today program.

The letter was initiated by MEPs Barry Andrews (Renew Europe), Lara Wolters and Niels Fuglsang (Socialists and Democrats) and is now being circulated among lawmakers to gather signatures. The deadline for submitting signatures is 18:00 Central European Time on Wednesday.

The authors of the appeal are demanding that football associations ensure that “FIFA officials are held accountable if evidence is found of violations of political neutrality rules.”

The lawmakers also recalled another appeal signed by 50 Members of the European Parliament, which called on FIFA to investigate the decision to award President Trump the FIFA Peace Prize.
