HOUSTON — Beyoncé told a packed stadium on Friday that it was time for America to elect Kamala Harris president, urging voters to “sing a new song,” before the vice president delivered a message to battleground voters all the way from reliably Republican Texas — that Donald Trump was dead set on eroding women’s rights.

“For all the men and women in this room, and watching around the country, we need you,” Beyoncé said.

The music megastar, who was joined by her mother, Tina Knowles, and her former bandmate Kelly Rowland, told the cheering crowd she wasn’t at the rally as a celebrity, or as a politician.

“I’m here as a mother,” Beyoncé said, talking about how her children would see “the sacrifices made so we can witness the strength of a woman ... reimagining what leadership is.”

Harris came out to huge cheers. She told the crowd that Trump had erased half a century of hard-fought progress when he appointed the Supreme Court justices who overturned Roe v. Wade and touched off a healthcare crisis.
