Donald Trump is travelling to the shrub-dotted hills of Arizona near the US-Mexico border to campaign on immigration, his signature issue since launching his first successful presidential bid nine years ago.
The visit is the fourth in a series of events held in battleground states this week to try to draw the focus away from Democrats’ celebration of Vice President Kamala Harris’ presidential nomination in Chicago.
The Trump campaign placed a lectern with a sign that says “the southern border” on a dirt road between a border wall and piles of steel beams.
The theme of Thursday’s visit is “Make America Safe Again,” and Mr Trump plans to meet with people whose relatives were attacked or slain by immigrants who arrived in the country illegally during the Biden administration.
Nearby, snipers stood at an elevated position, their eyes and weapons pointed towards Mexico.
On Wednesday, the GOP nominee held his first outdoor rally since an assassination attempt, speaking to supporters while surrounded by bulletproof glass.
Mr Trump and his Republican allies are criticising Ms Harris and other Democrats for spending more time talking about him this week at the Democratic National Convention than talking about issues like the border and immigration.
“It’s like they’re having a party. They don’t mention the border. All they do is make up lies about me,” Mr Trump complained as he called into Fox & Friends on Thursday morning.
Some of the speakers at the convention on Wednesday accused Mr Trump of using the border to stir up his base.
They argued that Democrats are the ones offering “real leadership” while Mr Trump demonises immigrants.
“When it comes to the border, hear me when I say, ‘You know nothing, Donald Trump,'” said Veronica Escobar, who represents the border city of El Paso, Texas.
“He and his Republican imitators see the border and immigration as a political opportunity to exploit instead of an issue to address.”
Senator Chris Murphy, a Connecticut Democrat, spoke after a video played showing Republican opposition to a bipartisan border deal earlier this year.
Mr Murphy was the top Democrat negotiating the proposal with conservative senators and said the bill would have had unanimous support if it were not for Mr Trump.
Mr Trump has spent the week campaigning across the battleground states.
He travelled to Pennsylvania, Michigan and North Carolina and will hold events in Las Vegas and the Phoenix suburb of Glendale on Friday.
His running mate, Senator JD Vance of Ohio, spoke at the same location near the border a few weeks ago.
