Donald Trump has taken a broad swipe at those who are questioning his authority, attacking the mainstream media, the "radical left", looters and thugs.
Tens of thousands have taken to the streets of US cities for an eighth consecutive night over the death of a black man in police custody, as curfews failed to hold back people expressing anger and grief.
Large marches and rallies took place in New York, Washington, Los Angeles, Philadelphia, Atlanta and Seattle, invoking the name of George Floyd, and other police victims.
On Monday night, five police officers were hit by gunfire in two cities.
Trump has been widely condemned for clearing protesters with force from outside the White House for a photo opportunity at a nearby church.
