The following quotation is from the Los Angeles Times in 2016, but it might still be valid: "It's official. El Salvador is the world's most violent country and its capital, San Salvador, is the world's most homicidal city. Salvadoran cities have seen more blood spilled than most conflict zones. They are also hemorrhaging people, many of whom are fleeing to Mexico and the United States."
It sounds like more refugees for President Trump to deal with.
