In anticipation of the huge queues of traffic, vendors set up their stalls of Trump merchandise as far as 10 miles away from the rally site.

Cars and trucks filled with “Trump 2024” flags and caps, and signs reading “Let’s Go Brandon”, a Republican code for “f— Joe Biden” tooted their horns in support as they travelled along the desert road to the Country Thunder fairground.

“It’s just a party atmosphere,” said Jonathan Riches, who was attending his 40th Trump rally.

“It’s almost like a MAGA Woodstock. It’s patriots from around the country getting together for the common good of this country. We love our president.”

Jennifer Winterbauer, who was first in line to get into the rally, said she had come to hear “the truth” from Trump.

“He always gives the truth about everything. The economy, the state of the world, the United States,” she said.

In the more than hour-long speech, Mr Trump also lobbied attacks on Mr Biden, saying under his leadership the US had become “a laughing stock all over the world”.

The Biden administration, he said, was “wreaking havoc on our economy, going mandate-crazy” and allowing crime waves to rock US cities.
