U.S. President Donald Trump said Monday that replacing embattled FIFA President Gianni Infantino would be “a terrible mistake,” throwing his support behind the football chief as he faces mounting criticism from several of the sport’s leading confederations.

Infantino came under renewed pressure after UEFA, CONCACAF and the AFC signed an open letter accusing the FIFA president of breaking trust “through deception.” The three confederations represent football in Europe, North and Central America, and Asia, respectively.

Despite the backlash, Trump defended Infantino, who presented the U.S. president with a “FIFA Peace Prize” during last year’s World Cup draw ceremony.

Infantino has also faced scrutiny over his unsuccessful efforts to sell a stake in the World Cup to private investors, adding to the growing controversy surrounding his leadership of world football.

“FIFA would be making a terrible mistake if, for any reason, they even considered replacing President Gianni Infantino,” Trump posted on Truth Social.
