BOSTON (AP) — William Bulger was once one of Massachusetts' most powerful politicians, ruling the state Senate for nearly two decades with a razor wit and legislative arm-twisting.

For the past few years, Bulger's legacy as Senate president and former head of the five-campus University of Massachusetts system has been eclipsed by the prosecution of his brother, convicted Boston mobster James "Whitey" Bulger.

Throughout his older brother's summer-long trial, William Bulger has been noticeably absent. He's made no public statements and hasn't talked to the press.

Other family members have attended the trial, including another Bulger brother, John "Jackie" Bulger, and several of William Bulger's children.

Bulger was convicted Monday in federal court on 11 killings and other gangland crimes including extortion. Massachusetts prosecutors are weighing whether to pursue state murder charges against him.
