Harris ripped by Trump campaign after Beyoncé doesn't perform at packed rally: 'They lied to build a crowd'

"Beyoncé went up and spoke for a couple of minutes and then left, and the place went crazy," Trump told a crowd in Michigan. "They booed the hell out of everybody. They thought she was going to perform. What happened was my opponent got up and started speaking, and they booed the hell out of her. It's crazy. They have to use people to get people to come, and then they send buses. We don't send buses. Everybody comes. We're just going to make America great again. It's very simple."

Several media outlets, including MSNBC, promoted Beyonce's appearance with Harris in Houston on Friday by saying that the music superstar would perform, prompting criticism from conservatives who accused Harris of intentionally misleading the public. Beyoncé did speak, but she did not perform. 

"Promising a concert from a huge pop star who then did not perform is the most perfect metaphor for the Harris campaign that anyone could dream up, only it really happened," Murtaugh added.

The Harris-Walz campaign issued a press release on Saturday following Trump's Michigan rally calling the former president "uhinged."

"As Vice President Harris draws record crowds and bridges divides, Trump showed again today that he is too busy trying to divide our country to lead it," Harris-Walz campaign spokesperson Sarafina Chitika.

"America can't afford to let an unhinged and unchecked Complainer-in-Chief back into the White House to enact his revenge. While Trump adds to his enemies list, Vice President Harris is bringing voters together across party lines because she is focused on actually helping the American people as President."

"It's time for America to sing a new song," Beyoncé said as she formally endorsed the vice president in her White House race against Trump. "Ladies and gentlemen, please give a big, loud, Texas welcome to the next President of the United States, Vice President Kamala Harris."

And she emphasized that "I'm not here as a celebrity, I'm not here as a politician, I'm here as a mother. A mother who cares deeply about the world my children and all of our children live in. A world where we have the freedom to control our bodies."
