2:09 PM PT -- Police tell us they arrested the man and charged him with carrying a dangerous weapon, carrying a rifle or shotgun outside a business, possession of unregistered ammunition and possession of a large capacity ammunition feeding device.
Vice President Kamala Harris could have been in danger Wednesday afternoon ... the Secret Service tells us agents detained a man outside the Veep's D.C. residence and cops say he had guns and ammo.
The agents stopped the man around 1 PM ET near the Naval Observatory, which is the traditional Vice President's mansion. Cops say they found a firearm, a bunch of ammo and several gun clips with ammo in the man's car, which was parked in a D.C. garage.
Fortunately, the Veep wasn't at the Naval Observatory when agents nabbed the man -- the mansion is getting a bunch of repairs so she and Second Gentleman Doug Emhoff have been living at Blair House ... a 19th-century row house steps away from the White House.
The Vice Prez was working Wednesday in the Eisenhower Executive Office Building, which is right next to Blair House.
Story developing ...
