PALM BEACH, Fla. (AP) — Donald Trump has recommitted to debating Vice President Kamala Harris after recently backing out. The Republican presidential nominee held a lengthy news conference Thursday in which he taunted his new rival, boasted of his crowd on Jan. 6, 2021, and lashed out at questions about the enthusiasm her campaign has been generating. As he addressed reporters at his Palm Beach, Florida, estate, ABC announced that Trump and Harris have agreed to a Sept. 10 presidential debate. In taking questions from reporters for more than an hour, Trump tried to draw a contrast with Harris, who has not held a news conference since she became the likely Democratic nominee following President Joe Biden’s withdrawal from the race.
