Donald Trump slams Joe Biden's immigration policies in first rally since leaving White House

Former US president Donald Trump blasted the Biden administration's immigration policies and sought to energise Republicans to take back majorities in Congress next year.

Appearing to relish being back in front of thousands of supporters, Trump repeated his false claim that his defeat in the November 2020 election was marred by fraud.

Trump left office in the aftermath of the deadly Jan. 6 attack on the U.S. Capitol by his supporters, shortly after a speech in which he urged a crowd to "fight" when then President-elect Joe Biden's victory was about to be certified by lawmakers.

Trump survived a second impeachment on a charge linked to the violence and has kept broad influence over the Republican Party, in part by leaving open the question of whether he will run for office again in 2024.
