Beyoncé on Friday lent her star power to Kamala Harris at a high-octane rally in her native Texas, declaring that the country was on the “brink of history” as the vice-president warned the state’s near-total abortion ban could become the law of the land if Donald Trump is elected.

“For all the men and women in this room, and watching around the country, we need you,” Beyoncé told a crowd of 30,000 people at the open-air Shell Energy stadium in Houston.

With the presidential race effectively deadlocked, Harris detoured from her frenetic race across the seven battleground states to appear in reliably Republican Texas, where she sought to highlight the state’s abortion restrictions for voters who have yet to make up their minds or cast a ballot.

“Let us be clear: If Donald Trump wins again, he will ban abortion nationwide,” Harris told the audience, her largest to date. Harris walked on to the stage, as she has ever since she became the presumptive nominee roughly 100 days ago, to Beyoncé’s hard-charging anthem, Freedom.

Harris has centered her campaign on the theme of freedom. In the closing days of the campaign, she has painted Trump as posing a threat to hard-won progress, eroding access to reproductive care, seeking to walk back LGBTQ rights and targeting American democracy itself. Earlier this week, Harris agreed that Trump was a “fascist”.

Harris spoke to an exuberant crowd, thousands of whom had waited hours in the sticky Houston heat to attend. Rally-goers were given flashing wristbands in all different colors. They danced and sang as a DJ spun pop ballads before the event began.

But the message Harris came to deliver was sobering. She listed the sprawling impacts of abortion bans like the one in Texas, which she called “ground zero for the right for reproductive freedom.”

“All that to say, elections matter,” Harris said.

Despite the speculation, the megastar did not perform. “I’m here as a mother,” Beyoncé said. “We are at the precipice of an incredible shift, the brink of history,” Beyoncé told the roaring crowd.

In the final days before the election, the Harris campaign is tapping the star power of the party’s most popular figures and celebrity supporters. On Friday night, Willie Nelson, the country music star and Texas resident, performed his best-known songs, including On the Road Again and actor Jessica Alba urged women to vote. Beyoncé was joined by her mother, Tina Knowles, and her former bandmate Kelly Rowland.

“We are grabbing back the pen from those who are trying to write an American story that would deny the right for women to make our own decisions about our bodies,” Rowland said. “Today that means grabbing that pen and casting my vote for Kamala Harris.”

The night before, Harris held her first campaign event with Barack Obama. They were joined onstage in Atlanta by rocker Bruce Springsteen, who played a three-song set and branded Trump an “American tyrant.” On Saturday, Harris will rally with Michelle Obama in Michigan.

Harris does not expect to win Texas. But Democrats here are suddenly hopeful after polls suggest an unexpectedly close senate race between the Republican incumbent, Ted Cruz, and the Democrat, Dallas-area congressman Colin Allred.

Democrats face a daunting senate map this cycle. With a loss in West Virginia all but certain, and Montana slipping out of reach, their hopes of maintaining narrow-control of the Senate may rest on an upset in the Lone Star state.

“Everything is bigger in Texas,” Allred said on Friday night. “But Ted Cruz is too small for Texas.”

The emotional heart of the evening was the personal stories of Texas women who had nearly died from pregnancy-related complications because they did not receive proper care.

Ondrea, a Texas woman who appeared in a new Harris campaign, became emotional as she shared her harrowing experience after a miscarriage at 16 weeks and needing an emergency abortion that she was denied under the state’s law. A video played before her remarks showed her with a wound and scars that stretched down her body, from her breast to her pelvis, after a six-hour surgery in which she said doctors had to cut open her torso in order to save her life.

Texas residents Amanda and Josh Zurawski, who have become powerful surrogates for Harris on the campaign trail, also shared their story. At 18 weeks pregnant, Amanda Zurawski began to suffer complications and needed an abortion. There was no chance the foetus would survive, but doctors refused to terminate the pregnancy until she eventually developed sepsis, days later.

“I was finally close enough to death to deserve healthcare in Texas,” Amanda Zurawski said.

Todd Ivey, a reproductive health specialist in Houston, addressed the crowd surrounded by a team of doctors and medical professionals in white lab coats. He emphasized the challenges of administering care to patients when it could mean risking arrest. Since the Texas law took effect the state’s infant mortality has risen.

“This is a healthcare crisis,” he said. This is unacceptable and it is cruel.”

Among those in the crowd was Sara Gonzales, 32, of Splendora, Texas, who drove to the stadium straight from an early-morning shift at Starbucks. Gonzales said she considers herself an independent and in 2020, wrote in a candidate for president. But the political stakes changed, Gonzales said, the supreme court overturned Roe v Wade, and Texas enacted its near-total ban on abortion.

“Being a woman in Texas right now, it’s not OK,” she said. “I should have freedom over my own body.”
