Ozil has called out the Chinese government over their alleged abuses against ethnic Uighur Muslims.
The weekend defeat to Manchester City ended up being axed from state television, with Ozil also being removed from the internet.
The Chinese government fiercely denies all allegations of mistreatment against Uighur Muslims.
But US chief Pompeo has come forward to offer his support to Ozil.
“The CCP can't hide its gross human rights violations perpetrated against Uighurs and other religious faiths from the world."
The Ivorian, who has been playing for Chinese club Qingdao Huanghai, said: “Footballers have to stay with football and politicians to politics because you cannot be involved with this kind of things.
“It's going to attract a lot of problems and a lot of things.
“As a Muslim it's complicated and it's his choice. He's been doing his comments but I think he was wrong to say that."
Meanwhile, Uighur children have thanked Ozil for speaking up.
