Laura Loomer: Who is conspiracy theorist travelling with Trump?

Another source, however, told the outlet that Ms Loomer did not interfere in debate preparations and said she was a “positive person to be around”.

Dennis Lennox, a Republican consultant, was much more pointed in his criticism of Trump’s debate performance and Ms Loomer. “That’s what happens when you wing it, live in the Fox News-X bubble, and rely upon Matt Gaetz, let alone Laura Loomer,” he told Semafor.

Ms Loomer did not respond to several requests for comment from the BBC.

But on X, formerly Twitter, she said that she operates “independently” to help Trump, who she referred to as “truly our nation’s last hope”.

“To the many reporters who are calling me and obsessively asking me to talk to them today, the answer is no,” she wrote. “I am very busy working on my stories and investigations and don’t have time to entertain your conspiracy theories.”

Born in Arizona in 1993, the self-styled investigative journalist has worked as an activist and commentator for organisations including Project Veritas and Alex Jones’s Infowars.

In 2020, she ran – with Trump’s support – as a Republican candidate for the US House of Representatives in Florida, but lost to Democrat Lois Frankel.

She tried again two years later, when she unsuccessfully ran to unseat Representative Daniel Webster in a Republican primary in a different Florida district.
