According to the Daily Mail, the head of Trump's World Cup organizing committee publicly supported Argentina, taking a side in the controversy surrounding the banners in the Falklands.
After Argentina defeated England 2-1 in the World Cup semi-final, the Argentine players displayed a banner that read " The Falkland Islands belong to Argentina ," which sparked strong dissatisfaction from the British side after the match.
However, Andrew Giuliani, the head of the White House FIFA task force under the US president, has now sided with Argentina.
He told reporters in Washington today: "In the United States of America, we believe in the rights granted by the First Amendment."
"In terms of the ability to express a position and make a voice heard, Argentina has such a right in the United States."
FIFA rules prohibit any political messages at the World Cup, but have previously turned a blind eye to some potential violations. Argentina was previously filmed singing a song about the 1982 conflict and posting it on social media.
Whether FIFA will complete its investigation before Sunday's final against Spain and whether it will impose penalties remains to be seen. The Daily Mail's sports department has contacted FIFA for confirmation.
A FIFA spokesperson said: "In accordance with standard procedure, the FIFA Independent Disciplinary Committee is currently reviewing the match report and considering the relevant circumstances before deciding on possible subsequent measures in accordance with the FIFA Disciplinary Code."
