The national guard is under the complete control of the president. The governor can deploy them.
But the President at anytime can take control over those units. Governors act like a commander. But the President is the commander and chief.
That being said, If Trump didn't want the national guard they wouldn't be. There is ~15,000 soldiers in DC ( not fucking normal ) the only reason why they would be there is if Trump wants them there. Trump wouldn't designate an emergency in DC if it wasn't in his favor.
Anyone who claims to be close to the president who hasn't back stabbed him says he will be president for the next four years. Anyone who claims that has been silenced to include the Q people.
One thing I know is Trump seems to always have a Plan. I have faith he does and I'll follow that plan.

I went back and re-read your post. I like your optimism. I hope you're right. I hope the troops are in DC for a reason - to protect and serve President Trump and ensure that Trump has a smooth transition into his 2nd term. It would make sense to have national guard troops in DC, on hand, to make sure that he can put down any attempt at insurrection that may occur.
