A US judge banned a humanitarian activist from mentioning President Donald Trump in court yesterday, where he stands accused of harbouring undocumented migrants in the country illegally. 

Dr Scott Warren, 37, appeared in Tucson Federal Court in Arizona for a second time this year on Tuesday after the first ended in a deadlocked jury in July. 

US district court judge Raner Collins passed the prosecutors’ motion to forbid Dr Warren mentioning the far-right president.
