U.S. Vice President Harris, who formally accepted the Democratic presidential nomination, elaborated on her "most detailed" statement on U.S. foreign policy to date at the Democratic National Convention in Chicago. During the convention, Harris and her allies in the party continued to attack former U.S. President and Republican presidential candidate Trump, accusing him of "kowtowing" to foreign countries, endangering "democracy" and betraying American "values."

According to a report by The New York Times on August 23rd, Trump also watched the live broadcast that night, and these were obviously things he didn't like to see. Shortly after Harris scolded him as "an unserious person", Trump picked up the phone and called the conservative media Fox News. Then, during Fox News' live broadcast of the Democratic National Convention, there appeared a segment that the liberal media The New York Times described as "aimless, stream-of-consciousness rebuttal".

"She said all these things, 'We're going to do this, we're going to do that, we're going to do everything,' but she didn't do anything!" Trump complained directly on the live broadcast: "She didn't talk about China, she didn't talk about fracking (fracking, a technology for extracting oil and gas from shale, is a dividing point on the issue of clean energy in the US presidential election), and she didn't talk about crime."

According to reports, the live call was arranged temporarily, and the producer had just confirmed the connection less than half an hour before Harris gave her speech. The entire call lasted 10 minutes until Fox News informed Trump that "there was no time left".

During the call, Fox News anchors Bret Baier and Martha MacCallum tried to interrupt several times to ask questions, but Trump ignored them several times and kept talking to himself.

Trump also objected when McCallum noted that Harris had "had some success" among women, Hispanics and black voters. "She's not having success, I'm having success," he said. "I'm doing well with Hispanics, I'm doing well with blacks, I'm doing well with women. That's just in your eyes, Martha, we're doing great."

During the call, Trump's speech was interrupted several times by "beeping" sounds, as if the former president accidentally pressed a key on the phone's keyboard.

In the end, anchor Baier had to take the initiative to end the connection before Trump finished speaking. Fox News then switched to a late-night comedy show, and the host Greg Gutfeld joked to the audience: "That (cut) is not my fault, Donald Trump. By the way, he's still talking."

During Harris' speech and before his call with Fox News, Trump could no longer suppress his desire to criticize Harris and posted real-time comments on his social media platform Truth Social.
