Tito Jackson, the former District 7 councillor and 2017 candidate for mayor, is among three Roxbury civic leaders who say they’re backing state Rep. Nika Elugardo in the Democratic primary for the Second Suffolk Senate seat.

As a city councillor, Jackson represented parts of Dorchester, the South End, Fenway and Roxbury. He is now the CEO of Verdant Medical, a marijuana company.

The other two endorsers are Dorothea Jones, a longtime member of the Democratic State Committee, and Angie Camacho, who ran for City Council last year.

Elugardo is vying for the state Senate seat alongside fellow state Rep. Liz Miranda, senior pastor Miniard Culpepper and former state Sen. Dianne Wilkerson. The Second Suffolk Senate district includes Dorchester, Mattapan, Roxbury, Mission Hill and Jamaica Plain’s Hyde Square.

“There’s not a badder sister in the State House right now, and this is not about personalities, this is about her ability to deliver for the people of this district,” Jackson, a former aide to Gov. Deval Patrick, said in a statement. “When Nika Elugardo is our Senator, we will be headed in the right direction.”

Added Jones: “Nika has a long history of building economic power in black and brown communities and that is exactly what we need in our next State Senator. Nika has proven herself to be a leader who builds up others and delivers on her promises with integrity and compassion.”

Former acting mayor Kim Janey, longtime activist Mel King, the Massachusetts Teachers Association and Jamaica Plain Progressives have previously endorsed Elugardo.

Miranda has been endorsed by the current District 7 councillor, Tania Fernandes Anderson; Massachusetts Nurses Association; City Councillor At-Large Ruthzee Louijeune; and former state Rep. Jeffrey Sanchez, who chaired the House Ways and Means Committee while at the State House.

The primary is set for Tuesday, Sept. 6.
