Trump referred to his Secretary Defense Mark Esper as Esperanto. He repeated false claims that US soldiers being withdrawn from Syria were coming home when they were actually redeployed to Iraq, and that some kind of source of oil had been secured without any further explanation. The tweet has since been deleted.

Trump has also misspelled his wife’s name and his own name.
