Former first daughter Barbara Pierce Bush has not only endorsed Kamala Harris for president but spent part of last weekend campaigning for the vice president in Pennsylvania, People magazine reported Tuesday.

Barbara Bush, 42, is the daughter of former President George W. Bush and granddaughter of former President George H.W. Bush, both Republicans.

In a statement to People, Barbara Bush said: “It was inspiring to join friends and meet voters with the Harris-Walz campaign in Pennsylvania this weekend. I’m hopeful they'll move our country forward and protect women’s rights.”

Her endorsement is the latest in a string of children of prominent Republicans who support Harris, a Democrat.

In a statement last week, Susan Ford Bales, the daughter of former President Gerald Ford, said: “America cannot regress back to a divisive paradigm of loathing toward one another and disdain for our Constitution. We witnessed on January 6 the horrors of what that looks like, and we can never allow a repeat of that tragedy.”

Jimmy McCain, son of the late Sen. John McCain, who was the 2008 Republican nominee for president, announced in September he has registered as a Democrat and will vote for Harris. 

“I’m a center man who cares about his country more than anything,” McCain said.

And former Vice President Dick Cheney and his daughter Liz Cheney, a former Republican congresswoman from Wyoming, have crossed the aisle to back Harris. Liz Cheney has also campaigned with the vice president.

“I tell you, I have never voted for a Democrat, but this year, I am proudly casting my vote for Vice President Kamala Harris,” Liz Cheney said at a campaign event earlier this month in Ripon, Wisconsin. 

The former congresswoman has been a vocal critic of Trump’s efforts to overturn the 2020 election.

A married mother of two, Barbara Bush is a nonprofit leader and author. 

Her father has not endorsed a candidate in the election.
