Taliesin Myrddin Namkai-Meche, 23, and Rick Best, 53, were fatally stabbed on Friday while intervening to stop a racist attack on a Muslim teenager on a commuter train.
The pair have been honoured as heroes by Portlands mayor and the FBI, and were the subjects of a candlelit vigil in the city on Saturday night. The president had until Monday remained silent, despite tweeting 10 times on Sunday on topics including healthcare, fake news and the Montana special election which was won this week by the Republican candidate, after he had assaulted a Guardian reporter.
Throughout Sunday, pressure mounted on social media for Trump to make a statement on the attack, which was carried out by a suspected white supremacist, Jeremy Christian, 35.
Dan Rather, the veteran American journalist, led the charge on Facebook, calling on Trump to acknowledge the brave Americans who died at the hands of someone who, when all the facts are collected, we may have every right to call a terrorist.
