Kantor Leaves Mike Ross For Ayanna

Boston City Council president Mike Ross confirms for me that his chief-of-staff, Reuben Kantor, is leaving to join the Ayanna Pressley campaign for at-large city council. 

Kantor, who joined the political arena just a few years ago, has quickly become one of the city's top progressive operatives. "Ayanna will really benefit from Reuben's strength on both the political and the policy side," says Ross, who endorsed Pressley the night of the preliminary election.

Kantor will not be returning to the position after November's election -- Ross says he is in the process of finding a new chief of staff.
