He needs to lead instead of taking a backseat. The Left took over the narrative.
He can use the power of the federal government. The federal government make states do lots of things. For the riots he can use the army or various federal law enforcement agencies to stop them. It is an insurrection. He can use the bully pulpit. I am sure there are federal assets the can use.
The story is about the tyranny of Democrat govs, which usually a president can correctly only influence.
