Mike Bloomberg is putting up cash prizes to find out who will be America's most influential Mayor.
The former New York City Mayor's foundation will hold a contest — and award $17 million to mayors who address some of the country's biggest challenges.
One city will take home a $5 million grand prize, while dozens of others will win smaller amounts.
Mayors are encouraged to address critical issues like climate change, obesity, and illegal guns.
The new contest is part of a larger $200 million initiative aimed at helping America's cities that Bloomberg plans to unveil today at the U.S. Conference of Mayors in Miami.
The billionaire is increasingly using his personal fortune to encourage policymakers to work around Washington and President Trump.
