LOS ANGELES — US Olympic officials reaffirmed Boston as America's 2024 Summer Olympics bid candidate despite more opposition than support from area citizens, hopeful a revamped plan from organizers will win public support. US Olympic Committee (USOC) Chief Executive Scott Blackmun and USOC Chairman Larry Probst said Tuesday after a quarterly USOC board meeting that they have not spoken with any other losing finalist as a backup plan ahead of September's deadline to submit bids to the International Olympic Committee (IOC). “We're focused exclusively on Boston,” Blackmun said. “We haven't had conversations with Los Angeles, Washington or San Francisco. Boston is our partner.” — Reuters
