Internal documents obtained by The Washington Post and reported on Tuesday reveal a secret Pentagon plan by the Trump administration to create a standing force of military personnel that could be rapidly deployed to U.S. cities or communities to quell public protests or any situation President Donald Trump deems "domestic civil unrest."

The proposal to create what it dubs a "Domestic Civil Disturbance Quick Reaction Force"—which evidence shows has been under serious consideration by the administration over recent months—would utilize existing statute, including invocation of Title 32, to authorize the deployment of specialized National Guard units anywhere in the country within hours, according to the documents.

"You don't want to normalize routine military participation in law enforcement," Nunn warned. "You don't want to normalize routine domestic deployment."

"When you have this tool waiting at your fingertips, you're going to want to use it,” he added. "It actually makes it more likely that you're going to see domestic deployments—because why else have a task force?"
