President Trump on Wednesday said he has ordered both the FBI and the Department of Justice to investigate the death of George Floyd, the Minnesota black man who died in police custody earlier this week and whose death has sparked national outrage.

"At my request, the FBI and the Department of Justice are already well into an investigation as to the very sad and tragic death in Minnesota of George Floyd," Trump tweeted.

Trump earlier in the day called Floyd's death a "very, very sad" situation during a trip to Florida for the launch of the SpaceX rocket ship. (The launch was delayed due to inclement weather after he arrived.)

The president's tweet also came after presumptive Democratic presidential nominee Joe Biden called on the DOJ's Civil Rights Division to investigate the death of Floyd.

Biden said Floyd's death was "part of an ingrained, systemic cycle of injustice that still exists in this country" and "cuts at the very heart of our sacred belief that all Americans are equal in rights."
