Hundreds of migrants were filmed cheering triumphantly as they packed out a cargo train heading toward the US amid record numbers of illegal border crossings.Footage posted by Fox News on Sunday showed a FerroMex train passing through the central Mexican city of Zacatecas as it made its way northbound on a 750-mile journey to the US.Each cargo carriage was packed with people cheering, clapping and whistling in apparent triumph — with some even hanging from the sides and waving at the camera.The footage quickly went viral after being tweeted by Fox News’ Griff Jenkins, who wrote that the migrants were “clearly not heeding the message: ‘do not come.'”He was referring to Vice President Kamala Harris who told Guatemalan migrants in June: “Do not come. Do not come. The United States will continue to enforce our laws and secure our borders.” The Post has reached out to US Customs and Border Protection for comment.The video comes amid unprecedented illegal immigration to the United States. In August, US Border Patrol officials arrested at least 91,000 migrants who crossed the border as part of family groups, according to data obtained by the Washington Post — beating the previous one-month record of 84,486 migrant families arrested in May 2019, under the Trump administration.
