A Boston City Councilor who said he’s been let down by the organizers behind the Boston 2024 Olympics bid is preparing to subpoena the group to get access to what he says could be crucial information about what financial resources city taxpayers could be on the line for.

Dorchester and Roxbury City Councilor Tito Jackson has filed an order with the city clerk to force the Boston 2024 group to release two chapters of the initial bid proposal it gave to the national Olympic committee. Chapters five and six from the so-called “1.0” bid document have been under wraps since the pro-Boston Olympics group presented it to the United States Olympic Committee in December 2014.

“I am again calling on Boston 2024 to show us the financial aid package,” Jackson said at a press conference outside Boston City Hall Monday morning. “We deserve to understand what was promised to be delivered by the taxpayers of the city of Boston.”

Without the documents being made public, it’s hard to know exactly what the chapters say, but Jackson says he wants to know the organizers made no financial commitment when vying to become the United States bid.

Boston 2024 did not respond to requests for comment on Jackson’s move to subpoena the group.

Outside City Hall, Jackson compared the Boston 2024 bid to a private company trying to do business without fully disclosing its financial plans.

“I am disappointed that Boston 2024, a group of individuals who no one has elected, would make financial promises, commitments and speculations on behalf of the City of Boston and have the audacity to tell us it is none of our business,” Jackson said in a statement.

If Jackson’s subpoena is to go forward, it needs to be approved by the entire 13-member council.
