US Republican lawmakers unveiled an immigration package that would tighten border security, end chain migration and fund President Donald Trump's border wall while shielding nearly a million so-called Dreamers from deportation. <br/><br/>The legislation was introduced just minutes after Trump said that any legislation that protects such undocumented immigrants would need to fund a wall along the US-Mexico border one of the primary pledges of his 2016 presidential campaign. <br/><br/>Trump told reporters at the White House that any solution has to include the wall because, without the wall, it all does not work. US need the wall for security and safety.<br/><br/>Congress is grappling with how to break an impasse over the Dreamers immigrants who were brought to the United States illegally as children but were permitted to stay under Barack Obama's Deferred Action for Childhood Arrivals (DACA) program.<br/><br/>Trump scrapped DACA last September but left a six-month window for Congress to craft a solution by March, when thousands of immigrants would face deportation.<br/><br/>As lawmakers race against time to find a fix, a US judge late yesterday blocked Trump from scrapping DACA and ordered it maintained on a nationwide basis, as legal challenges against it proceed. But the White House and Democrats agreed that the ruling does not diminish the urgent need to resolve the issue.
