Portland attack: Calls mount for Donald Trump to address fatal stabbing of 'brave men' who tried to protect Muslim teenager on train

Pressure is mounting on Donald Trump to address the fatal stabbing of several men who tried to protect a Muslim teenager from being subject to a racist rant on a train. 53-year-old Ricky Best and 23-year-old Taliesin Myrddin Namkai-Meche were killed after they tried to stop Jeremy Christian from hurling abuse at two women, one of whom was wearing a hijab. A third passenger, 21-year-old Micah David-Cole Fletcher, was wounded.
