#1 He would handle FIFA's Twitter handle
Donald Trump just loves using Twitter. He has posted more unnecessary and derogatory tweets during his time as the POTUS than he has made sensible decisions that protects the good of people. Whenever one reads his tweet, she/he goes into further bewilderment as to how he ever became a president.
Since he loves using the social media app so much, he would take over the official Twitter account of FIFA and use it as a means to insult anyone and anything that he doesn’t remotely like – which ranges from Mexicans, women and people that follow a certain religion.
He wouldn’t tweet about anything that acknowledges the achievement of the aforementioned things that he doesn’t like, and would heap praise on ethnic Caucasian players for something as trivial as going to the toilet – which, by the way, he finds disgusting when a woman does it.
