A$AP Rocky's trial began in Sweden yesterday and, according to The Guardian, President Donald Trump has sent a presidential envoy for hostage affairs to the hearing.

Special envoy Robert O'Brien arrived at Stockholm's district court on Tuesday to monitor the rapper's trial. US embassy spokeswoman Ruth Newman clarified to Swedish news agency TT that the envoy was there “to look after the wellbeing of American citizens, which is always our top priority."

Rocky pleaded not guilty to the aggravated assault charges he faces. His lawyer Slobodan Jovicic told the court that while the rapper admits to throwing alleged victim Mustafa Jafari to the ground, he and his two entourage members also involved in the case acted in self-defense.
