Former President Donald Trump is set to announce his running mate and hold campaign rallies leading up to the Republican convention in Milwaukee. However, his campaign's plans have been overshadowed by the Democratic Party's turmoil following President Joe Biden's poor debate performance. Trump's selection for a vice presidential candidate has narrowed to North Dakota Governor Doug Burgum, Florida Senator Marco Rubio, and Ohio Senator J.D. Vance. Trump and his advisors are reevaluating their VP choices as they anticipate the possibility of facing Kamala Harris as the Democratic nominee.
