On May 29, local time, when Biden condoled to the families of the victims at the scene of the Texas elementary school shooting, the people shouted "do something" at the scene.

Twenty-one people were killed in a shooting at Rob Elementary School in Uvalde, Texas.

Faced with the chants, Biden gave the crowd a thumbs up.

At present, the US Department of Justice has announced that it will launch a "critical incident review" of the matter.
