This latest arrest at the GOP convention came amid an ongoing investigation into the failed assassination attempt on Mr Trump.
In his first interview since the assassination attempt on Donald Trump, U.S. President Joe Biden has accused his political archrival of inciting the American public.

The incident has attracted global condemnation as U.S. authorities promise to investigate further.
