President Donald Trump attacked his own Federal Reserve chairman as an "enemy" of the United States amid his escalating trade war with China -- and other social media users were flabbergasted.

Fed chairman Jerome Powell refused to budge on interest rates, despite heavy pressure by the president in the face of a looming recession, and China retaliated against the tariffs Trump imposed with a new round of their own.

Trump lashed out at Powell, whose name he misspelled, and compared him unfavorably to Chinese leader Xi Jinping.

Other Twitter users were alarmed by the spectacle.
