An active duty military police battalion consisting of 200 to 250 military personnel is now in the process of deploying to Washington, DC, and could be in the nation's capital as soon as tonight, three US defense officials tell CNN.

The troops are expected to provide security in the nation's capital but not perform law enforcement duties such as arrest and detention of protesters or rioters.

Two defense officials said the troops will be coming from a unit at Fort Bragg in North Carolina.

Because of Washington, DC's unique status, the deployment does not require local authorization.

I've read about his threats to send federal troops where they are not wanted.  What part of law and order does he not comprehend?

Ah, thank you.  I'm trying to restock my new refrigerator and post and read and watch TV and now it's treatment time...trying to stretch too far,

Cuomo may go around DeBlasio after his poor performance  in NYC.  Political infighting.

Cuomo Hypothesizes About Overthrowing de Blasio After NYC Riots: 'Police Did Not Do Their Job Last Night'

"The police did not do their job last night," Cuomo said after rampant looting and destruction swept across Manhattan on Monday night.

If it is domestic terrorism he has an obligation to act.

And Trump may overthrow several governors, including Cuomo, using the US military to install martial law across the country.

If it is a danger to the country, he must do that.  If the governors want to avoid it they can fix the problem themselves.  They have warning and they have time.

Why is Cuomo's comments political infighting but Donald Trump threatening even stronger military action against several governors reacting to terrorism?

Because they are on the same side. Two Democrats fighting are in fighting.

You're taking two different positions on the same behavior.  Trump giving notice he is thinking about doing it is his duty, but Cuomo giving notice he is thinking about doing it is political infighting.  Cuomo has a duty to protect the citizens of NY City as strong as a president's duty to protect all citizens.

No, it makes perfect sense to me. Two Democrats should conceivably be willing to work together for the same goals because their beliefs are the same or similar.  Trumps is different because he likes to get things done.  It may not be true but from what I’m seeing, governors in blue states, which is sadly where most of the serious destruction is, appear to be giving destroyers a pass.
