GOP wants to hold Harris’s immigration record against her - what did she do?

US vice-president has been called a border czar' by Trump and a champion for Dreamers' by immigration advocates

This week the House passed a Republican-led resolution condemning Kamala Harris for her role in the Biden administration's handling of migration, part of a ramped up effort to portray the presumptive Democratic nominee as dangerously lax on border security.

Following Joe Biden's decision to bow out of the presidential race, Donald Trump has also unleashed a barrage of fresh attacks on the US vice-president's record on immigration, a politically volatile issue expected to play a central role in the November presidential election.
