Former President Donald Trump has denounced Vice President Kamala Harris’ nomination as the Democratic presidential candidate as “not fair,” escalating his rhetoric as new polls show Harris gaining substantial ground in key battleground states.

In a fiery statement on his social media platform Truth Social, Trump accused the Democratic Party of staging “the first ever ‘Coup’ in America.”

His outburst comes in the wake of President Joe Biden’s unexpected withdrawal from the 2024 race, which paved the way for Harris to become the Democratic nominee.
