Sick children, families and businesses are among the many people in Haiti, a country plagued by gang violence, likely to be hit hard by a U.S. travel ban.

When Trump included Haiti in a list of countries on which he was imposing a near-total travel ban, some saw a culmination of a long campaign against the population.

The Trump administration announced in a proclamation on Wednesday that it will ban nationals from Haiti from entering the United States and partially limit Cubans and Venezuelans from coming into the country.
