Trump says he's agreed to Fox News debate with Kamala Harris on September 4 in Pennsylvania arena | 3 Aug 2024 | Donald Trump has said he's debating Kamala Harris on September 4. The GOP nominee claims the face-to-face will take place in an arena in Pennsylvania, but Harris has yet to confirm it's happening. Posting on Truth Social Friday night, Trump wrote: "I have agreed with FoxNews to debate Kamala Harris on Wednesday, September 4th." Trump claims that the ABC News debate scheduled for September 10 was "terminated" when Biden dropped out of the race. He also claimed that there's a conflict of interest because he's in litigation against ABC and anchor George Stephanopoulos, who Trump has referred to as "Slopadopoulos."
