Former President Donald Trump criticized Vice President Kamala Harris's speech at the Democratic National Convention in a series of posts on Truth Social. Trump accused Harris of avoiding key issues like China, fracking, and energy, while also labeling her as a "radical Marxist" and "incompetent." He argued that Harris failed to address the real problems facing the country and mocked her previous leadership in San Francisco. Harris criticized Trump as an "unserious man". He warned that his return to the White House would prioritize his self-interest over national security and the well-being of the American people.
