The prominent Donald Trump supporter and private security executive Erik Prince says he has a 10-year deal with Haiti to fight the country's criminal gangs, and then take a role in restoring the country's tax-collection system.

The security firm of former U.S. Navy SEAL Erik Prince will soon deploy nearly 200 personnel from various countries to Haiti as part of a deal to quell gang violence there, a person with knowledge of the plans said Thursday.

Erik Prince said his firm, Vectus Global, will run security operations and manage tax collection under a 10-year contract with Haiti. However, the Blackwater founder did not provide details on the cost to Haitians.
