Protecting Mr. Trump in a prison environment would involve keeping him separate from other inmates, as well as screening his food and other personal items, officials said. If he were to be imprisoned, a detail of agents would work 24 hours a day, seven days a week, rotating in and out of the facility, several officials said. While firearms are strictly prohibited in prisons, the agents would, most likely, nonetheless be armed.
Former corrections officials said there were several New York state prisons and city jails that have been closed or partly closed, leaving large sections of their facilities empty. One of those buildings could serve to incarcerate the former president and accommodate his Secret Service protective detail.
Anthony Guglielmi, the spokesman for the Secret Service in Washington, declined in a statement to discuss specific “protective operations.” But he has emphasized that federal law requires Secret Service agents to protect former presidents, adding that they use state-of-the-art technology, intelligence and tactics to do so.
Thomas J. Mailey, a spokesman for New York State’s prison agency, has said that his department could not speculate about how it would treat someone who has not yet been sentenced, but that it has a system “to assess and provide for individuals’ medical, mental health and security needs.” Frank Dwyer, a spokesman for the New York City jails agency, recently said only that “the department would find appropriate housing” for the former president.
While each count carries the possibility of up to four years in prison, Justice Merchan would most likely order any sentence to run concurrently, meaning Mr. Trump would serve prison time on each of the counts simultaneously. Under normal circumstances, any sentence of one year or less would generally be served on New York City’s notorious Rikers Island, home to the Department of Correction’s seven jails. (That’s where Mr. Trump’s former chief financial officer, Allen H. Weisselberg, 76, is serving his second five-month sentence for perjury.)
