The trial for ASAP Rocky has finally begun in Sweden, and the rapper has pleaded not guilty to the assault of a "fan" who harassed and allegedly assaulted Rocky and his team.

Rocky's lawyer maintains the rapper was acting in self-defense.

The case shocked fans across the globe, and even President Trump claimed that he tried to intervene on Rocky's behalf but to no avail:

"Very disappointed in Prime Minister Stefan Löfven for being unable to act. Sweden has let our African American Community down in the United States. I watched the tapes of A$AP Rocky, and he was being followed and harassed by troublemakers. Treat Americans fairly! #FreeRocky," he tweeted last week.

Rocky could face up to two years behind bars if he is convicted.

His trial began on Tuesday and is expected to last for three days. 

The trial was being held in a secure courtroom "because of the large interest from the media and the public," the Stockholm court said per NBC. No photographing or filming was permitted inside the courtroom.
