BOSTON — The group pushing to bring the 2024 Summer Olympics to Boston raised nearly $2.9 million during the first quarter of 2015, and spent just over $2 million, according to a report released Friday by Boston 2024.

The biggest donors were John and Cyndy Fish, who contributed between $1 million and $2 million. John Fish is a construction magnate and the group’s former leader.

Six people earn more than $100,000, including the CEO, former state transportation boss Richard Davey, who gets $300,000.
