How the MS-13 gang spread from Los Angeles to New York

During President Trump’s State of the Union on Tuesday night, he talked about two teenage girls on Long Island who were murdered by MS-13 gang members in 2016. Their parents were in the House chamber during the speech. Trump mentioned MS-13 four times, saying members have long taken advantage of immigration loopholes to enter the US and threaten safety. However, MS-13 was actually formed in Los Angeles in the 1980s.
