He once wore ultraluxury clothes, including a $33,000 blue lizard jacket, an $18,000 suede coat and $12,000 suits, but will likely trade in his federal prison garb for a drab khaki shirt and trousers at Rikers.

It is unclear precisely how long Mr. Manafort would be held at Rikers, although he is expected to await his trial in New York.

A law enforcement official familiar with the jail’s practices said he would probably be held in one of the oldest buildings in the island, known as the North Infirmary Command, which was built in the early 1930s, or in one of the complex’s newest structures, a set of fiberglass tent-like structures known as “Sprungs.”

Cell blocks in the infirmary command have eight cells and a day room with a television on each tier, the official said. The inmates are not locked in their cells during the day.

In March, a Manhattan grand jury handed up an indictment charging Mr. Manafort with 16 state felonies, including residential mortgage fraud, and accusing him of a yearlong scheme in which he allegedly falsified business records to obtain millions of dollars in loans. The new case was brought by the Manhattan district attorney, Cyrus R. Vance Jr.

The president has broad power to issue pardons for federal crimes, but has no such authority in state cases.

While Mr. Trump has not said he intends to pardon his former campaign chairman, he has often spoken of his power to pardon and has defended Mr. Manafort on a number of occasions, calling him a “brave man.”
