The Secret Service has vacated its command post inside Trump Tower and relocated to a nearby New York sidewalk after a dispute with President Trump's company over the terms of the lease, according to a report Thursday.

The Secret Service command post, which stations supervisors and backup agents in case of an emergency, had been located in a unit one floor below the president's apartment in Trump Tower.

In early July, the Secret Service moved the post to a trailer on the sidewalk, a distance that concerns security experts interviewed by the Washington Post.

A spokeswoman for the Trump Organization told the Post the Secret Service should lease space elsewhere outside Trump Tower.

"After much consideration, it was mutually determined that it would be more cost effective and logistically practical for the Secret Service to lease space elsewhere," spokeswoman Amanda Miller said.

The details of the lease dispute are not clear, but the Post said there are disagreements over the price of the lease.

Secret Service officials downplayed the impact of the lease dispute, telling the Post the agency is still hoping for space in Trump Tower.

The Secret Service is aiming "to obtain permanent work space in an appropriate location," said Catherine Milhoan, a Secret Service spokeswoman. "Throughout this process, there has been no impact to the security plan developed by the Secret Service."
