He also removed Rep. Charles Murphy of Burlington as chairman of the budget-setting Ways and Means Committee. Instead, he will be majority whip.

Both Vallee and Murphy have courted their fellow Democrats in case DeLeo leaves, angering the speaker. DeLeo also was upset after internal deliberations during the chamber’s gambling debate leaked to the media.
