they belong to the states
"the texas national guard" for example
the president has the power to call up any state's national guard to quell unrest, stifle rebellion, or fend off invasion.
he deployed the California National Guard in los angeles during the recent immigration riots (which was both unrest and invasion)
in DC it's a little different, they can supplement the local police force at the president's command, just like the california's national guard can supplement the local police force at either the governor's or president's command - but for the president to do it requires some of those circumstances I mentioned earlier. civil unrest, not just crime. the line is a little blurry because gangsters quickly turn into warlords when a population cannot defend itself, like in haiti.
