Bryon Hefner, whose criminal case sparked a reckoning on Beacon Hill and engulfed the political career of his once–powerful husband, is weighing a guilty plea ahead of his trial on multiple counts of sexual assault, court officials say.

Hefner and prosecutors are scheduled to appear Sept. 10 in Suffolk Superior Court — one day before jury selection is scheduled to begin — for what a court clerk said Tuesday is a possible change of plea.

Hefner, the husband of former Senate president Stanley C. Rosenberg, has pleaded not guilty to nine counts of sexual assault and other misconduct, including allegations he repeatedly groped two men against their will and forcibly kissed a third.
