Mr Floyd, who was African-American, died in Minneapolis on May 25 while in police custody.

Speaking at the White House, he said: “Mayors and governors must establish an overwhelming law enforcement presence until the violence has been quelled.

“If a city or state refuses to take the actions that are necessary to defend the life and property of their residents, then I will deploy the United States military and quickly solve the problem for them.”

Mr Trump then walked to the nearby St John’s Church and posed for pictures while holding a bible.
