Hours after Donald Trump was sworn in for a second term, he issued an executive order laying the groundwork for mass deportations of immigrants and denying them legal assistance.

Public interest groups focused on immigrant rights teamed up to fight the order and called in Gibson Dunn, a major law firm with the resources to help take on the White House. In January, Gibson Dunn, working with the groups, sued the Trump administration seeking to restore legal help for immigrants facing deportation.
