Previously, the Secret Service had stationed its command post — which houses supervisors and backup agents on standby in case of an emergency — in a Trump Tower unit one floor below the president's apartment.

But in early July, the post was relocated to a trailer on the sidewalk, more than 50 floors below, a distance that some security experts worry could hamper the agency that protects the president's home and family.

The command post appears unlikely to move anytime soon back inside Trump Tower, where the president and his family have rarely gone since moving to the White House.

On Thursday, a spokeswoman for the Trump Organization said the government should seek space in another location.
