Prosecutors told a Boston federal judge on Tuesday that they could put accused Boston Marathon bomber Dzhokhar Tsarnaev on trial next fall, while defense lawyers said they need much more time for discovery and to possibly seek a new venue.

During a 90-minute, wide-ranging motion hearing and status conference, government lawyers pressed the court to set deadlines. They also fended off arguments that jailhouse rules unduly restrict Tsarnaev’s lawyers and that government responses to discovery requests were inadequate.
