Quincy: US Senate Candidates, State Treasurer expected to visit Labor Union convention

The day after a new AFL-CIO President was elected, several key players in Massachusetts government plan to attend the labor union’s annual conference in Quincy.

Massachusetts Treasurer Steven Grossman plans to speak at the Massachusetts AFL-CIO’s 54th Annual Constitutional Convention, at about 1:15 p.m. Thursday at the Quincy Marriott.

Later in the day, a tentative agenda for the convention lists the U.S. Senate Democratic candidates set to challenge incumbent Republican Sen. Scott Brown as scheduled to appear at 4 p.m.

Those candidates include Harvard law professor Elizabeth Warren, City Year cofounder Alan Khazei, immigration attorney Marisa DeFranco, state Rep. Tom Conroy, GOP incumbent and Newton resident Herb Robinson, and self-described “social justice advocate” Robert Massie.

The state’s largest union, which represents about 400,000 workers around the state, will be led by Senator Steven Tolman, who succeeds outgoing president Robert Haynes. Tolman is in his seventh term in the Senate after two terms in the House.
