U.S. Olympic Committee leaders are in Boston to meet with 2024 Summer Olympics planners to see what progress they're making in turning Massachusetts public opinion in their favor.

USOC chairman Larry Probst and CEO Scott Blackmun are expected to meet privately Thursday with Boston 2024 Chairman Steve Pagliuca and CEO Rich Davey.

Probst promised after a June 30 meeting in California with Boston organizers they would be "circling back" on efforts to gain local support, which sits at about 42 percent statewide.

A group of residents is also speaking Thursday about their efforts to get a question placed on the 2016 ballot banning taxpayer spending on the estimated $4.6 billion games.

Boston is America's pick to compete for the 2024 games with Paris, Rome, Hamburg, Germany, and Budapest, Hungary.
