The wife of the Afghan-born U.S. citizen charged in last weekend's bombings in New York City and New Jersey has returned to the United States, a law enforcement official said on Thursday, as a defense lawyer pressed to get access to the accused man.

Ahmad Khan Rahami, 28, has been held in a Newark, New Jersey, hospital since being arrested on Monday with wounds after a shootout with police. Rahami faces federal charges in both states stemming from a Saturday night bombing in Manhattan's Chelsea neighborhood that injured 31 people and explosives found in two New Jersey locations. No one was killed in the blasts.

Rahami's wife, Asia Bibi Rahami, flew back to the United States overnight, a law enforcement official said. She had voluntarily met with U.S. law enforcement authorities while in the United Arab Emirates this week and gave a statement.
