"So far this fiscal year, 481 gang members have been apprehended trying to cross our border illegally", the statement read. "This crisis is endangering the safety of American families".
The gang members are crossing with up to 1 million migrants from three Central American countries – El Salvador, Guatemala and Honduras – who are expected to enter the US illegally this year in a bid for political asylum, according to US officials.
The MS-13 gang — previously known as La Mara Salvatrucha — reportedly emerged in 2012 as transnational criminal organization.
The Trump administration has claimed that MS-13 had more than 10,000 members, mostly immigrants or the children of immigrants from El Salvador, Guatemala and Honduras.
In March, US President Donald Trump declared a national emergency and requested $32.5 billion in funds for border security in fiscal year 2020, including $8.6 billion for building a border wall. Trump insisted that the wall is needed to prevent criminals and terrorists from crossing into the United States.
