Donald Trump has been criticised for sharing videos of white Americans being attacked by black men, and asking "where are the protesters?" just days after a campaign speech peppered with racial stereotypes raised fears that race will be weaponised in this year's US election.
The US president took to Twitter to retweet a video of a white employee being assaulted at a Macy's store in Michigan.
In that incident, the attacker's brother alleged that the employee used a racial slur prior to the assault.
Macy's denied the claim, saying the attack was "unprovoked".
Trump retweeted the video, saying: "Looks what's going on here. Where are the protesters?"
