George W. Bush's daughter, Barbara Pierce Bush, 42, joined the Harris campaign last weekend in Pennsylvania to help knock on doors and campaign for the potential future Democratic president.
Bush's endorsement of Vice President Kamala Harris came after her mother and father said they had no plans to endorse either candidate for office.
They did not vote for either candidate in 2016, writing "None Of The Above" on their ballots.
This cycle, a significant cohort of staffers from the administrations of former Presidents George W. and George H.W. Bush have thrown their weight behind Harris, including a former Cabinet member.
"It was inspiring to join friends and meet voters with the Harris-Walz campaign in Pennsylvania this weekend," Bush told People magazine Tuesday.
"I’m hopeful they'll move our country forward and protect women’s rights."
In a photo circulating online, Bush could be seen standing at the front stoop of a home with several others, while donning a "Kamala" hat.
