who was responsible for getting the us player reinstated
The person most widely reported as responsible was President Donald Trump , who called FIFA president Gianni Infantino and asked for the U.S. player’s suspension to be reviewed, after which the ban was suspended.
What happened
Reports say the player was Folarin Balogun , and FIFA then lifted or suspended the red-card ban so he could play in the next match.
Who else was involved
Gianni Infantino, as FIFA president, made the decision on the FIFA side, but the reporting consistently points to Trump’s phone call as the key trigger for the review.
In plain terms
So, if you’re asking “who got the U.S. player reinstated,” the short answer is: Trump appears to have been the main person behind it, while FIFA formally carried out the reinstatement.
