The ultra-violent Latino street gang MS-13, which President Trump vowed to wipe out in a speech in suburban New York on Friday, is estimated to have some 10,000 members in the United States.Each of these units is loyal to the broader gang but has its own leader and functions differently, says Hector Silva of Insight Crime, a Washington-based center that studies organized crime in Latin America.Many were born in the United States.
