The top House Democrat, Minority Leader Nancy Pelosi, and her Democratic colleagues, want young immigrants to be protected again, as they negotiate a budget deal with US President Donald Trump's Republican Party.

Immigration is one of the biggest sticking points, including so-called "chain migration," or family-based immigration. It refers to a person bringing members of their family to the US after being granted residency.

Trump wants to put an end to it, but the president's own ancestors came to America that way.
