President Joe Biden and Vice President Kamala Harris will share the stage on Tuesday in Virginia as they campaign for abortion rights, a top issue for Democrats in an election expected to feature a rematch with Donald Trump, the former Republican president.

Biden and Harris will be joined by their spouses, first lady Jill Biden and second gentleman Doug Emhoff. It’s the first time the four of them have appeared together since the campaign began, a reflection of the importance that Democrats are putting on abortion this year.

Harris was in Wisconsin in Monday to mark the 51st anniversary of Roe v. Wade, the U.S. Supreme Court decision that legalized abortion nationwide. The decision was overturned two years ago, and Trump helped pave the way by nominating three conservative justices to the court during his term. He recently said he was “proud” of his role.

“Proud that women across our nation are suffering?” Harris said. “Proud that women have been robbed of a fundamental freedom? Proud that doctors could be thrown in prison for caring for their patients? That young women today have fewer rights than their mothers and grandmothers?”

Wisconsin was Harris’ first stop on what’s expected to be a nationwide tour focused on abortion, which she described as an integral part of the country’s tradition of personal liberty.

Abortion is also the focus of Biden’s new television advertisement featuring Dr. Austin Dennard, an OB-GYN in Texas who had to leave her state to get an abortion when she learned that her baby had a fatal condition called anencephaly.

“In Texas, you are forced to carry that pregnancy, and that is because of Donald Trump overturning Roe v. Wade,” Dennard said.
