Lawyers for James “Whitey” Bulger said Monday that they plan to file within the next few days a motion to postpone the notorious gangster’s long-awaited trial, saying they cannot review the thousands of pages of documents involved by the scheduled March trial date.

Bulger’s lawyers, led by J.W. Carney Jr., have complained of the struggle to prepare in time for the trial, but on Monday they said they will officially file a motion citing their reasons and legal arguments.
