The prominent Donald Trump supporter and private security executive Erik Prince says he plans to keep his forces in Haiti for 10 years under an arrangement that will eventually give his firm a role in the country's tax-collection system.

Vectus Global, a security company led by Erik Prince, has a contract to battle Haiti’s gangs and restore tax collection.

The deployment by Vectus Global is meant to help the government of Haiti recover vast swaths of territory seized in the past year and now controlled by heavily armed gangs.
