Edited sentence: In 2018, the gang accounted for less than 1 percent (10,000) of total gang members in the United States (1.4 million), and a similar share of gang murders.Republican politicians, President Trump in particular, have falsely accused Democratic politicians of supporting MS-13.The Trump administration and Republican politicians have argued that hardline immigration policies are necessary to combat MS-13, and have for example justified the Trump administration's implementation of a family separation policy to deal with MS-13.The gang is a core component to Republican Party messaging on immigration policy in the United States.There is no evidence that weak immigration enforcement or sanctuary city policies contribute to MS-13 activity
